Google Interview Questions
Back to company list
Alphabet (Google) uses advanced technology, analytics, and artificial intelligence to provide instant access to information through an extensive range of products and services, including YouTube, Cloud, and Android.
Given their high demand for data insights to drive business decisions, Google hires tech professionals who can handle a variety of roles, including developing models to improve Google’s search algorithms, voice recognition systems, and natural language processing (NLP) capabilities.
In this guide, we’ll cover a general overview of Google’s interview process, and then provide examples of common interview questions you may face across various topics.
Google Interview Process
Google’s interview process is designed to evaluate a candidate’s technical knowledge, critical thinking, and cultural fit. This multi-stage process generally includes:
- Preliminary Screening: This initial step is conducted by a recruiter to get a sense of a candidate’s background and potential fit.
- Technical Interviews: Several technical interviews (typically conducted over the phone) will be done to evaluate the depth of a candidate’s knowledge in areas like statistics, probability, basic coding, and machine learning algorithms.
- Onsite Interview: Following successful technical interviews, candidates are invited for onsite interviews, which consist of 4-6 back-to-back sessions. Here, they face a mix of technical and behavioral questions. Often, the interviewers will present hypothetical business problems to see how a candidate determines the correct metrics, business approach, and how well they justify their methodology.
Google’s interview process can be quite demanding due to its focus on statistical and technical skills. It’s worth noting that interviews are typically conducted without a specific role in mind at first, with a team-matching process occurring after successful interviews.
Google Interview Guides
Google case study interview questions.
Problem-solving is an essential skill for various tech roles at Google. Case study interview questions assess a candidate’s problem-solving abilities, analytical thinking, and application of technical knowledge to real-world scenarios.
- How would you assess the validity of a 0.04 p-value from an AB test?
Your company runs a standard control and variant AB test to increase conversion rates on the landing page, and the test yields a 0.04 p-value. Consider the factors behind conducting and measuring an AB test correctly.
- What features would you add or change to improve Google Maps?
Describe what metrics you would use to measure the success of the improvements.
- Determine if Youtube success is now limited to only “superstar” creators.
A Google product manager is concerned that amateur video creators aren’t able to achieve success on Youtube’s platform. What metrics or data would you assess to see if this is true?
- How would you troubleshoot a system that has slowed down?
As a leader in large-scale systems, Google’s software must scale in proportion to its demand. What are the first steps to consider whenever a system slows down?
When practicing for case studies, we recommend using the product metrics and data analytics learning paths.
Google Statistics & Probability Interview Questions
Statistics and probability are also common topics asked by Google. They are often included in data analyst, data scientist, and research scientist interviews.
- What are the expected outcomes of ad ratings from two types of raters?
In a scenario where ad ratings are performed by two types of raters (careful or lazy) with different probability patterns, calculate the expected number of good ads when:
- 100 raters each rate one ad independently
- One rater rates 100 ads
Additionally, find the probability that a lazy rater rated an ad given that it was rated as bad.
- Determine the fairness of a coin based on the outcome of 10 flips.
You flip a coin ten times, resulting in 8 tails and 2 heads. Based on this outcome, assess the fairness of the coin (i.e., p=0.5).
- What is the distribution and expected value of a double-random function?
You’re given a function that outputs a random integer between a minimum value, $N$, and a maximum value, $M$. If we use this function’s output as the max value in another random function with the same minimum value $N$, predict the distribution of the samples and the expected value.
To prepare for probability and statistics interview questions , check out the comprehensive probability learning path . It covers basic to advanced probability concepts, including multivariate distributions and sampling theorems.
Google Coding Interview Questions
Coding interview questions are commonly featured in data and software engineering positions at Google, as well as data scientist and other related roles. These questions typically cover data structures and algorithms, with a particular emphasis on tree and graph data structures. It’s important to know how to traverse, modify, and balance these data structures.
Write a function to merge two sorted lists into one. Given two sorted lists, write a function to merge them into one sorted list. What’s the time complexity?
Create a function can_shift to check if one string can be shifted to form another string. Given two strings A and B, write a function can_shift to determine if string A can be shifted a certain number of places to yield string B.
Develop an algorithm to move all disks from peg A to peg C following the Tower of Hanoi conditions. Given pegs A, B, C, and n disks, move all the pegs from peg A to peg C.

Google SQL Interview Questions
SQL is the industry standard for managing and manipulating databases. As such, interview questions can delve into a range of topics, including writing and optimizing SQL queries, data normalization, transaction control language commands, and indexing. Since effective database querying is an essential skill, SQL questions are asked for many roles during the interview process.
How can you find the last transaction for each day? You have a bank_transactions table with columns that include transaction_value and the transaction’s date and time. Create a query that retrieves the last transaction for each day, including the transaction id, datetime, and amount.
Write a query to select the second-highest salary in the engineering department. Using the employees and departments tables, write a query to find the second-highest salary in the engineering department. If the highest salary is shared by more than one person, your query should find the next unique highest salary.
Determine the Top 3 highest employee salaries per department . Using the employees and departments tables, write a SQL query to find the Top 3 highest salaries per department, with an output that includes the employee’s full name and department. For departments with less than 3 employees, return the highest or Top 2 salaries.

Google Machine Learning Interview Questions
Machine learning is an ever-evolving field that is integral to leveraging data for decision-making, trend identification, and customized user experiences. These questions are typically asked in data analyst, data scientist, and product analyst interviews.
How would you justify the complexity of a neural network model to non-technical stakeholders? You’re asked to build a model using a neural network to address a certain business problem. Justify this approach and explain the model’s predictions in a way that non-technical stakeholders can understand.
How are coefficients of logistic regression interpreted for categorical and boolean variables? Discuss the interpretation of coefficients in a logistic regression model, specifically for categorical and boolean variables.
What distinguishes Lasso from Ridge Regression? Outline the differences between these two common techniques in regularization.
To get ready for machine learning interview questions , we recommend reviewing the modeling and machine learning course .
Google Salaries by Position
Most data science positions fall under different position titles depending on the actual role.
From the graph we can see that on average the Product Manager role pays the most with a $182,008 base salary while the Business Analyst role on average pays the least with a $128,648 base salary.
Google’s Most Asked Questions
Practice for the Google interview with these recently asked interview questions.
When analyzing various interview experiences, we noticed that Google’s interview questions heavily emphasize data structures and algorithms questions, specifically traversal algorithms. Many interviewees reported that Google likes tinkering with hard questions, so be sure to practice your algorithms.
Some of the key concepts that you need to know to ace your Google Interview include:
Breadth-First Search and Depth-First Search
Breadth-First Search (BFS) and Depth-First Search (DFS) are techniques for traversing and searching tree or graph data structures. Knowing them is critical to understanding a number of more complex algorithms.
- Breadth-First Search (BFS): BFS works by visiting all the nodes of a graph at the present “depth” before moving on to the nodes at the next depth level. It’s usually implemented using a queue data structure.
- Depth-First Search (DFS): DFS visits a node and then iterates on each of its neighbors. If a neighbor hasn’t been visited, the algorithm goes on to that neighbor and repeats the process until all nodes are visited. It’s often implemented using a stack or recursion.
Graph Traversal Algorithms
- BFS and DFS: As described above, these algorithms also apply to graphs.
- Dijkstra’s Algorithm: This is a weighted graph traversal algorithm used to find the shortest path from one node to all other nodes.
- A* Algorithm: A* is used in pathfinding and graph traversal, as it finds a path to the given goal node that has the smallest cost (usually in terms of distance).
Dynamic Programming
Dynamic programming is a method for solving complex problems by breaking them down into simpler subproblems. This approach seeks to solve each subproblem only once, saving its answer in a table (generally implemented as an array or some sort of map) to avoid redundant computations.
- Knapsack Problem: Given a set of items, each with a weight and a value, the goal is to determine the most valuable combination of items to include in a collection without exceeding a given weight limit. This classic problem can be tackled with both 0/1 Knapsack (items cannot be broken) and Fractional Knapsack (part of an item can be taken).
- Longest Common Subsequence (LCS): This problem involves finding the longest subsequence common to two sequences. Dynamic programming help reduce the time complexity of this problem.
- Fibonacci Sequence: Dynamic programming is often used to calculate the $n^{th}$ Fibonacci number efficiently.

By Mike Simpson
Updated 6/22/2022.
Every year, Google receives about 3 million applications. That’s only a little less than the entire population of Silicon Valley, which comes in just below 3.1 million .
Plus, only about 0.2 percent of those applicants are hired. Now, 0.2 percent of 3 million is 6,000 people, so that’s a ton of hiring. Plus, not every applicant is actually qualified, so your odds might be much better than that statistic shows if you are.
But beating the odds isn’t something you’ll do by accident. You have to be ready to nail the Google interview questions. Here’s how to pull that off.
Google Interview Process
The Google hiring process is a well-oiled machine, honed over years and years of looking for the best and brightest. While there can be some variation from one role to the next, the bulk of the process is typically similar.
First, most technical candidates will take a short skills assessment. For example, you might have to complete a coding quiz if you’re looking at certain software development roles.
After that comes a short phone or video interview or two. Usually, you’ll speak with a recruiter first. If that goes well, you might have a quick chat with the hiring manager or a potential colleague.
Next, you might need to complete a small project. Again, this is more common with specific roles, such as programming or marketing jobs. However, everyone should be prepared for another assessment to be safe.
If the project goes well, it’s time for an in-depth interview. Actually, it’s a series of interviews – potentially three or four – all possibly happening in one day. It’s intense, but it can also be a great chance to see what Google has to offer.
Once that’s all done, they’ll decide whether to extend an offer. If so, you’ll be contacted with the details.
How to Answer Google Interview Questions
Before we dig into some examples, let’s take a moment to talk about how you should answer Google interview questions. After all, Google has a reputation for asking some strange ones, many of which felt more like brain teasers than real interview questions.
Do you feel adequately prepared to talk about how many golf balls it would take to fill up a school bus? Probably not. The mere idea of facing off against a question like that would rightfully leave any candidate nervous.
Now, some of the questions were deemed so difficult that the company eventually banned them (lucky for today’s candidates, we think). Plus, there is evidence that these bizarre hypotheticals don’t actually lead to better hiring, which may be why you don’t see as many of those tricks today.
So, that means you don’t have to worry, right? Well, no. Even if you’re only going to face “normal” interview questions, that doesn’t mean you shouldn’t have a strategy. It’s also important to prepare, increasing the odds that you’ll impress during your Google interview.
Let’s start with the basics. If you want to stand out for all of the right reasons, research is your friend. Start by scouring over the Google job description. That way, you can learn the ins and outs of what the hiring manager needs to find, giving you all of the foundational tools you need to incorporate the right details into your answers.
Next, take it up a notch by reviewing th e company’s mission and values statements . You’ll find out more about the organization’s mentality, priorities, perspective, and culture , and additional tidbits you can weave into your responses.
Finally, get on social media. Look at Google’s profiles for insights about recent accomplishments, and even do a quick news search for more details. If you can discuss a new achievement during an interview, there’s a decent chance you’ll impress.
Alright, now you have a ton of information, what do you do with it? Well, if you’re asked a straightforward interview question, it’s pretty easy. For example, if the hiring manager wants to know if you have a skill, start with a simple “yes” or “no.” With the former, add an overview of how you acquired or used the skill. With the latter, pivot by discussing your willingness to learn or any steps you’re taking to improve in that area. Done!
But what about behavioral interview questions? Well, here’s what you need to know.
Google Behavioral Interview Questions
Overall, Google loves behavioral interview questions. They help hiring managers learn more about how you think and what you would do in specific situations.
Plus, most Google behavioral interview questions ask you to describe past experiences . Since many people think past success predicts future potential, it’s not a surprise that behavioral interview questions might make up the bulk of your Google interview.
Okay, but how do you handle those tricky behavioral interview questions ? Those don’t have “right” or “wrong” answers in most cases, so what do you do?
The key here is to adopt the right strategy. Take the STAR Method and then combine it with the Tailoring Method . Together, those let you create meaningful, engaging, relevant answers, increasing the odds that you’ll make a good impression during your interview.

Top 3 Google Interview Questions
Now, it’s important to note that the Google interview questions you face will vary depending on the position. They aren’t going to ask a software engineer the same set of questions they’ll use when hiring a recruiter.
However, certain questions are more common, applying to a range of niches. Here’s a look at the top three Google interview questions you may encounter.
1. What is your favorite Google product? What would you do to improve it?
This is a question that helps the hiring manager gauge your familiarity with Google’s offerings. Luckily, any Google product will do, as long as you can speak about it with enthusiasm and provide a relevant recommendation.
EXAMPLE ANSWER:
“My favorite Google product is YouTube. The platform itself is incredibly engaging, while also empowering for those who want to share their thoughts, talents, and tips. I’ve personally used it extensively to find answers to questions, gain new skills, or simply enjoy some entertainment. As for how I would improve YouTube, I would create an option for refining what videos are recommended. For example, clicking on a single video on a new topic can cause a feed to get flooded, even if the person no longer has an interest in that topic. Implementing the ability to request that YouTube show a person less content that is similar to a particular video would potentially alleviate this problem.”
2. Who do you believe are Google’s main competitors? How does Google stand apart?
With this question, the hiring manager can determine whether you have a solid idea of which other companies dominate spaces where Google also sits. This can be especially relevant in product-oriented roles, including everything from product manager positions to software developer jobs, where finding opportunities to outshine other companies comes with the territory.
“Google has several main competitors, including Microsoft, Facebook, Netflix, Waze, and several others, depending on the specific space. One of the main differentiators is Google’s ability to integrate its services, creating a cohesive cross-platform experience. Additionally, Google has such a wide range of offerings. It promotes a degree of familiarity you don’t necessarily get with some of the competitors, making using the products and platforms feel like a natural part of daily life.”
3. How do you make sure that you are your colleagues remain accountable?
Accountability is critical in the eyes of every employer. Google wants to know that you’ll handle your tasks and hold yourself to a reasonable standard. Additionally, the hiring manager may favor candidates who can also help team members stay accountable, especially if group projects are the norm.
“For me, accountability is always a priority. One of the key steps I take is to track all of my deliverables and associated due dates. A list allows me to create notifications and block out time on my calendar as necessary, ensuring I can focus on the task and finish on time. When a project is larger, I also use the mini-milestone approach. This creates an opportunity for me to examine each step along the way, making it easier to chart a course. As far as when I’m working with my colleagues, I find that follow up is often effective. At times, this many involve scheduling team meetings to discuss our progress or transition work between coworkers, or simply reaching out to see if they are on target or if I can offer assistance.”

A case study interview isn’t your average interview. While most interviews ask you to give examples of how you use your skills on the job, in a case study interview, you’ll use those skills in front of the interviewer to solve a real-life problem.
It’s like auditioning for the school play. But instead of showing you can sing and dance, you’re using a case interview to show how you provide innovative solutions to pressing business problems. Not sure how to get ready for this kind of interview? We’ve got you covered. This guide explains how to prep for a case study interview.
Case studies are used across a variety of industries — everything from business to medicine. They are an in-depth examination, analysis, and critique of a real-world scenario the company experienced. People discuss the situation and explore what they learned while forming new solutions to try when they face a similar situation in the future and hope to improve their performance.
For example, doctors and nurses use case studies to improve how they diagnose and treat patients. Using real patient information, the medical team analyzes the case to see what the team may have missed and why they missed it. Learning from these errors helps the team better prepare for similar cases in the future to improve patient care.
While many industries use case studies to iterate and improve their performance, not every company uses case study interviews. This type of interview is very common at consulting companies (no matter what kind of consulting it is). But it’s not unusual for companies outside of consulting to use case interviews for marketing or operations roles.
In a case study interview, you’re given a real-world situation the company has faced and are tasked with analyzing it and suggesting a course of action.
![case study interview questions google working at Accenture](https://www.theforage.com/blog/wp-content/uploads/2022/08/Accenture-150x100.jpg)
Future Innovator in Training
Experience what it's like to work as a consultant in this free course from Accenture. Help your client redesign a web page and improve the user experience.
Avg. Time: 5-6 hours
Skills you’ll build: Prioritizing, planning, data analysis, error spotting, communication, strategic thinking
Businesses use case study interviews to assess your abilities in real-time. While you’ll probably draw on a variety of skills, most case study interviews assess:
- Strategic thinking
- Analytical skills
- Common sense
The advantage of a case study interview is that the interviewer can evaluate your ability in each of these areas and see how you’ll actually use them on the job.
What Is a Fit Interview?
Some people use “case study interview” and “fit interview” interchangeably. While a fit interview and a case study interview both ask behavioral interview questions , they are not the same thing.
A case study interview assesses your ability to do the job. It primarily evaluates how you approach business problems and use your skills to solve them. A fit interview is about company culture fit. The interviewer asks questions that assess how well you’ll fit into the company, like asking you questions about what motivates you or how you lead .
Fit and case interviews are important parts of the evaluation process. Getting the job done is just as critical as getting along with coworkers and supporting the company’s mission. Depending on where you interview, you may have one fit interview and one case study interview, or the fit interview may be a smaller part of the case study interview.
What You’ll Learn in a Case Study Interview
A case study interview allows the hiring manager to see your skills in action and how you approach business challenges. But it also teaches you a lot about the company (even if you’re doing most of the talking).
In a sense, you’re behaving as an employee during a case study interview. This gives you a peek behind the curtain, allowing you to see the company’s inner workings, like how they approach business problems and what they expect from you and your performance.
For example, you may offer a novel approach to solving a problem during a case interview. How does the interviewer react to it? Are they impressed? Surprised? Is there a scowl or frown on their face? Their reaction gives you insights into how the company will likely receive your solutions.

Introduction to Strategy Consulting
Discover what consulting is all about in this free course from BCG. Learn how to reframe questions and challenge assumptions.
Avg. Time: 2 hours
Skills you’ll build: Critical thinking, creativity, brainstorming
Depending on the specific company, you may have the case study interview questions in advance, but you may not. Whether you do or don’t, here’s how to prepare for a case study interview.
Conduct Deep Research
Good interview prep for any interview means researching the company. That includes things like learning more about the company’s mission and the challenges the industry faces. But when you’re preparing for a case study interview, your research needs to go deeper.
When you answer a case study question, your answer has to be specific to the company’s clients or business objectives. For example, if you’re interviewing for a role in strategy consulting , your answer shouldn’t focus on aspects of human resources consulting (unless it’s particularly relevant).
Your research needs to include the kinds of clients the company works with and what types of problems the company solves. For example, the company may only consult for Fortune 100 companies that need accounting advice. Keep these facts in mind as you prepare for the interview.
Case Study Interview Formats
There are four types of case study interview formats:
- Candidate-led: The interviewer asks you a specific question (or gives you a prompt), and you walk the interviewer through a detailed answer.
- Employer-led: The interviewer leads you through a series of specific (and predetermined) prompts and questions, no matter your answers.
- Presentation: You’re given a problem in advance to create and present a detailed case study.
- Video: Similar to a presentation case study interview, you’ll create a video presentation of the case study.
Most companies will tell you in advance which style of case study interview you should prepare for. But if they don’t, reach out to your recruiter or check the company’s website. Many include the essential details you need to prepare for the case study interview.
Seek Out Company-Specific Tips
Speaking of companies and their websites, not only do many companies that use case study interviews tell you the format, they often include helpful tips and tricks to help candidates prepare. This includes what to expect, what the company is looking for skill-wise, and what kinds of responses they want. They may even have a few practice questions and videos you can use to help you prep.
Unlike other common interview questions , it’s not as easy to prepare an answer to case study interview questions. Even though you know it’s a case study interview, you don’t necessarily know the specifics of the case or what problems you’ll be asked to solve.

That said, it’s likely your case study interview questions will cover one or several of these concepts:
- Entering new markets
- Increasing profits
- Cutting costs
- Turnarounds
- Mergers and acquisitions
- Pricing strategy
- Developing new products
- Industry analysis
- Competitive response
While there are many ways to answer case study interview questions, a few basic prep tips can help you get ready for every question.
In addition to what you usually bring to a job interview , make sure you bring a notepad and pen or pencil to a case study interview. Taking notes will help you better understand the questions and formulate your answers. It also gives you a place to calculate numbers and figures if you need to. Not every case study interview allows calculators, so you’ll need to be ready to do your calculations manually.
Ask Specific Questions
As you’re working through the case study, you can and should ask any clarifying questions you need. The interviewer wants to hear specific, detailed answers that solve the problem. So, whenever you’re unclear, ask a follow-up question to not only get what you need but to give the interviewer what they need.
That said, your question(s) should be very specific. You need to verify exactly what the interview is asking so you can create an appropriate answer. Say the interviewer gives you a broad question: The client’s revenue is falling. How do you help them increase it? You can follow up with a very specific question or two to make sure you understand what the interviewer is asking:
You’re asking how I would help the client raise revenue, correct? Are you also asking how I would help them increase their profit and cut costs?

Talk Them Through It
A big part of the case study interview is seeing you in action. However, in this case, “see” really means “how you think.” Since the interviewer can’t hear your inner monologue, you’ll need to practice thinking out loud.
While the interviewer wants to hear your solution, they also want to hear how you got there. That means talking through your entire thought process. Instead of saying, “I’d do X,” you have to explain how you arrived at your decision while you’re getting there.
Because not everyone thinks out loud, it may feel unnatural to you, and you likely won’t be expected to do it on the job. But it’s crucial to practice this skill — and it is a skill — because the interviewer is expecting you to do it in a case study interview.

This is a complete guide to case interviews for beginners. Whether you have no idea what a case interview is or have just started preparing for consulting interviews, we’ll walk you through the case interview fundamentals.
Case interviews can seem complicated, confusing, and difficult to learn. However, with the right knowledge and strategies, case interviews can be fairly straight forward and mastered by anyone.
In this complete guide to case interviews for beginners, we’ll cover:

What is a case interview?
Case interviews are a special type of interview that every single consulting firm uses. They are almost exclusively used by consulting firms, although some companies with ex- consultants may also use them.
A case interview, also known as a “case” for short, is a 30 to 60-minute exercise in which you and the interviewer work together to develop a recommendation or answer to a business problem.
These business problems can be anything that real companies face:
- How can Amazon increase its profitability?
- What can Apple do to increase customer retention?
- How should Tesla price its new electric vehicle?
- Where should Disney open another Disneyland theme park?
Case interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that consulting firms solve for their clients. Many case interviews are based on actual projects that interviewers have worked on.
While consulting projects typically last between 3 to 9 months, case interviews condense solving the business problem into just 30 to 45 minutes.
Case interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.
They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.
Although case interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed.
Unless you are interviewing for a consulting firm that specializes in a particular industry or function, cases are designed to be solved by someone that has general business knowledge.
Nailing your case interviews is critical to getting into consulting . There is no way to get a consulting job offer without passing your case interviews.
What are examples of a case interview?
Here is an example of what a perfectly solved case interview looks like:
Here is another example of what a case interview looks like. This case interview is one where the interviewer leads most of the interview.
Here is a third example of a case interview. In this case interview, the candidate leads most of the interview. We’ll cover the difference between interviewer-led and candidate-led case interviews later in the article.
Finally, here is a fourth example of what a case interview looks like. This case is primarily focused on market sizing. We’ll cover what market sizing is and how to solve it later in the article.
Why are case interviews used?
Case interviews are the best way for consulting firms to predict which candidates will make the best consultants. Case interviews do not predict this perfectly, but they come quite close.
Since case interviews simulate the consulting job by placing you in a hypothetical business situation, interviewers use case interviews to see how you would perform as a hypothetical consultant.
Many of the skills and qualities needed to successfully complete a case interview are the same skills and qualities needed to successfully finish a consulting case project.
Case interviews also give you a sense of whether you would like the consulting job. If you find case interviews interesting and exciting, you’ll likely enjoy consulting. If you find case interviews dull and boring, consulting may not be the best profession for you.
What do case interviews assess?
Case interviews assess five different qualities or characteristics: logical and structured thinking, analytical problem solving, business acumen, communication skills, and personality and cultural fit.
1. Logical and structured thinking : Consultants need to be organized and methodical in order to work efficiently.
- Can you structure complex problems in a clear, simple way?
- Can you take tremendous amounts of information and data and identify the most important points?
- Can you use logic and reason to make appropriate conclusions?
2. Analytical problem solving : Consultants work with a tremendous amount of data and information in order to develop recommendations to complex problems.
- Can you read and interpret data well?
- Can you perform math computations smoothly and accurately?
- Can you conduct the right analyses to draw the right conclusions?
3. Business acumen : A strong business instinct helps consultants make the right decisions and develop the right recommendations.
- Do you have a basic understanding of fundamental business concepts?
- Do your conclusions and recommendations make sense from a business perspective?
4. Communication skills : Consultants need strong communication skills to collaborate with teammates and clients effectively.
- Can you communicate in a clear, concise way?
- Are you articulate in what you are saying?
5. Personality and cultural fit : Consultants spend a lot of time working closely in small teams. Having a personality and attitude that fits with the team makes the whole team work better together.
- Are you coachable and easy to work with?
- Are you pleasant to be around?
All of these five qualities can be assessed in just a 30 to 60-minute case interview. This is what makes case interviews so effective in assessing consulting candidates.
What companies give case interviews?
Case interviews are primarily used by management consulting firms (e.g., McKinsey, BCG, and Bain), but they are also used by some technology companies (e.g., Meta, Google) and private equity firms (e.g., KKR, Blackstone) that have a lot of ex-consultants.
Management consulting firms that give case interviews
- EY-Parthenon
- PwC and Strategy&
- Roland Berger
- Oliver Wyman
Technology companies that give case interviews
- Microsoft (including LinkedIn)
- Capital One
Private equity firms that give case interviews
- The Blackstone Group
- Bain Capital
When are case interviews given?
Case interviews are given in nearly every single round of interviews. During first round consulting interviews expect 1-2 case interviews. During final round consulting interviews , expect another 2-4 case interviews.
The only round of interviews that will not have a case interview is the initial phone screen with a recruiter. They will ask primarily resume and behavioral interview questions.
First round interviews are heavily focused on case interviews. There will typically be few behavioral or fit interview questions asked. Each case interview is typically 30 to 40 minutes each. Behavioral or fit interview questions may take up less than 10 minutes.
Final round interviews have a bit more focus on behavioral and fit interview questions, but the vast majority of time is still spent on case interviews. Each case interview is typically 40 to 60 minutes each. Behavioral or fit interview questions may take up to 40 minutes.
As you can see, case interviews are the primary way that management consulting firms assess and select candidates.
There are seven key components or steps of a case interview: understanding the case background, asking clarifying questions, structuring a framework, kicking off the case, solving quantitative problems, answering qualitative questions, and delivering a recommendation.
1. Understanding the case background
The case interview will begin with the interviewer giving you the case background information. Let’s say that the interviewer reads you the following:
Interviewer: Our client, Coca-Cola, is a large manufacturer and retailer of non-alcoholic beverages, such as sodas, juices, sports drinks, and teas. They have annual revenues of roughly $30 billion and an operating margin of roughly 30%. Coca-Cola is looking to grow and is considering entering the beer market in the United States. Should they enter?
As the interviewer reads this, take notes. It is important to understand what the objective of the case is and keep track of information.
One strategy for taking notes effectively is to turn your paper landscape and draw a vertical line to divide your paper into two sections. The first section should be roughly two-thirds of the page while the second section will be one-third of the page.
Take notes in the second section of your page:
![case study interview questions google Case interview note taking](https://files.cdn.thinkific.com/file_uploads/163260/images/27e/8d0/c35/Case_interview_note_taking.jpeg)
After the interviewer finishes giving the case background information, confirm that you understand the situation and objective. Provide a concise synthesis like the following:
You: To make sure I understand correctly, our client, Coca-Cola, is a large manufacturer and retailer of non-alcoholic beverages. They are looking to grow and our objective is to determine whether or not they should enter the U.S. beer market.
Interviewer: That sounds right.
Make sure your synthesis is concise. You do not want to regurgitate verbatim everything that the interviewer has said. Only mention the most important pieces of information.
You should also make sure you verify the objective of the case. Answering or solving the wrong case objective is the quickest way to fail a case interview.
2. Asking clarifying questions
Next in the case interview, you’ll have the opportunity to ask questions before you begin thinking about how to solve the case.
At this point, only ask questions that are critical for you to fully understand the case background and objective. You’ll be able to ask more questions later.
Types of questions you should ask:
- Asking for a definition of a term you’re unfamiliar with
- Asking for information that strengthens your understanding of the company or situation
- Asking questions that clarify the objective of the case
- Asking to repeat information you may have missed
You might ask a few questions like the following:
You: Is Coca-Cola looking to specifically grow revenues or profits?
Interviewer: Coca-Cola wants to grow profits.
You: Is there a particular financial goal or metric Coca-Cola is trying to reach within a certain time frame?
Interviewer: They are looking to grow annual profits by $2 billion within 5 years.
You: Great. Those are all the immediate questions I have for now.
3. Structuring a framework
After you understand the case background and objective of the case interview, lay out a framework of what areas you want to look into in order to answer or solve the case.
A case interview framework is simply a tool that helps you structure and break down complex problems into simpler, smaller components. Think of a framework as brainstorming different ideas and organizing them into different categories.
When creating a framework, it is completely acceptable to ask the interviewer for a few minutes of silence to write out a framework.
You: Would you mind if I take a few minutes to structure my thoughts and develop a framework to tackle this case?
Interviewer: Of course, go ahead.
For this case example, what do you need to know in order to help Coca-Cola decide whether or not they should enter the beer market?
You might brainstorm the following questions:
- Does Coca-Cola know how to produce beer?
- Would people buy beer made by Coca-Cola?
- Where would Coca Cola sell its beer?
- How much would it cost to enter the beer market?
- Will Coca-Cola be profitable from doing this?
- How can Coca-Cola outcompete competitors?
- What is the market size of the beer market?
This is not a very structured way of tackling the case, so organize these ideas into a framework that has 3 – 4 broad areas, also called “buckets”, that you want to investigate.
An easy way to develop these buckets is to ask yourself, what 3 – 4 things must be true for you to 100% recommend that Coca-Cola should enter the beer market.
In an ideal world. These four things would need to be true:
- The beer market is an attractive market with high profit margins
- Competitors are weak and Coca-Cola will be able to capture significant market share
- Coca-Cola has the capabilities to produce an outstanding beer product
- Coca-Cola will be extremely profitable
You can rephrase these points to be the broad categories in your framework. You can write your framework in the first section of your paper:
![case study interview questions google Case interview market entry framework](https://files.cdn.thinkific.com/file_uploads/163260/images/e05/503/bc9/Case_interview_market_entry_framework.jpeg)
Next, let’s add a few bullets under each category to give more detail on exactly what information we need to know to decide whether Coca-Cola should enter the beer market.
![case study interview questions google Case interview market entry full framework](https://files.cdn.thinkific.com/file_uploads/163260/images/84b/a10/d66/Case_interview_market_entry_full_framework.jpeg)
This entire process of brainstorming ideas and developing a structured framework should only take a few minutes.
How do you come up with a framework so quickly?
Most candidates make the mistake of either using a single memorized framework for every case or memorizing multiple different frameworks for different cases.
The issue with memorized frameworks is that they aren’t tailored to the specific case you are solving for. When given an atypical business problem, your framework elements will not be entirely relevant.
Interviewers can easily tell that you are regurgitating memorized information and not thinking critically.
Instead of memorizing frameworks, I recommend memorizing a list of 8 - 10 broad business elements, such as the following:
![case study interview questions google Case interview framework buckets](https://files.cdn.thinkific.com/file_uploads/163260/images/2e2/601/925/Case_interview_framework_buckets.jpeg)
When given a case, mentally run through this list and pick the 3-4 elements that are most relevant to the case. This will be your framework. If the list does not give you enough elements, brainstorm and add your own elements to your framework.
This strategy guarantees that your framework elements are relevant to the case. It also demonstrates that you can create unique, tailored frameworks for every business problem.
Using this strategy for this case, you would run through your list of memorized business elements and select the following:
![case study interview questions google Case interview framework example](https://files.cdn.thinkific.com/file_uploads/163260/images/76d/d75/fa0/Case_interview_framework_example.jpeg)
This strategy is a shortcut for creating unique tailored frameworks for every business problem. You do not need to develop a framework entirely from scratch every time.
Now that you have your framework, turn your paper to face the interviewer and walk them through it.
You: To decide whether or not Coca-Cola should enter the market, I want to look into four main areas.
One, I want to look into the beer market attractiveness. Is this an attractive market to enter? I’d want to look into areas such as the market size, growth rate, and profit margins.
Two, I want to look into the beer competitive landscape. Is this market competitive, and will Coca-Cola be able to capture meaningful market share? I want to look into questions such as the number of competitors, how much market share each competitor has, and whether competitors have any competitive advantages.
Three, I want to look into Coca-Cola’s capabilities. Do they have the capabilities to succeed in the beer market? I want to look into things such as whether they have the expertise to produce beer, whether they have the distribution channels to sell beer, and whether there are any existing synergies they can leverage.
Four, I want to look into expected profitability. Will Coca-Cola be profitable from entering the beer market? I want to look into areas such as expected revenues, expected costs, and how long it would take to break even.
The interviewer might ask a few questions on your framework, but will otherwise indicate whether they agree or disagree with your approach.
For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .
4. Kicking off the case
If this is an interviewer-led case, the interviewer will propose which area of your framework they would like to dive deeper into. They might say something like the following:
Interviewer: Your framework makes sense to me. Why don’t we start by estimating the size of the U.S. beer market.
If this is a candidate-led case, you will be expected to propose an area to look into. There is no right or wrong area to start first. Propose any area of your framework as long as you have a reason for it.
You could say something like:
You: To start, I’d like to look into the beer market attractiveness. I’d like to first understand the market size to determine if the beer market is an attractive market.
If you end up picking an area that the interviewer does not want you to explore, they will redirect you to an area that they do want you to explore.
The two styles of case interviews are nearly identical. The only difference is whether or not you have to proactively propose what area to explore first and what area you want to explore next.
5. Solving quantitative problems
Expect to perform calculations and analyze charts and graphs during your case interview.
Market sizing questions are one type of quantitative question you may get asked.
Let’s say the interviewer asks you:
Interviewer: What is the market size of beer in the U.S.?
Most candidates jump right into the math, stating the U.S. population and then performing various calculations. Doing math without laying out a structure often leads to making unnecessary calculations or reaching a dead-end.
Laying out an upfront approach helps avoid these mistakes and demonstrates that you are a logical, structured thinker.
For this market sizing problem, you could structure your approach in the following way:
- Start with the U.S. population
- Estimate the percentage that are legally allowed to drink alcohol
- Estimate the percentage that drink beer
- Estimate the frequency in which people drink beer
- Estimate the average price per can or bottle of beer
Multiplying these steps together gives you the answer. By laying out an approach up front, the interviewer can easily understand how you are thinking about the problem. With the right structure, the rest of the problem is simple arithmetic.
Sometimes the interviewer will give you numbers to use for these calculations. Other times, you’ll be expected to make assumptions or estimates.
When performing your calculations, make sure to do them on a separate sheet of paper. Calculations often get messy and you want to keep your original paper clean and organized.
A sample answer to this question could look like this:
You: To estimate the market size of beer in the U.S., I’m going to start with the U.S. population. Then, I’ll estimate the percentage that are eligible to drink alcohol. I’ll then estimate the percentage of the remaining population that drinks beer.
If we take this and multiply it by the frequency in which people drink beer and the average price per can or bottle of beer, we will find an estimate for the market size.
Does this approach make sense to you?
Interviewer: Makes sense to me.
You: Great. I’ll assume the U.S. population is 320M people. Assuming the average life expectancy is 80 years old and an even distribution of ages, roughly 75% of the population can legally drink alcohol.
This gives us 240M people. Of these, let’s assume 75% of people drink beer. That gives us 180M beer drinkers.
Let’s say on average, a person drinks five beers a week, or roughly 250 beers per year, assuming roughly 50 weeks per year.
This gives us 180M * 250 = 45B cans or bottles of beer.
Assuming the average can or bottle of beer costs $2, this gives a market size of $90B.
You should not only answer the question, but tie the answer to the case objective.
In other words, how does knowing the U.S. market size of beer help you decide whether or not Coca-Cola should enter the market?
You could say something like the following:
You: Given that Coca-Cola has annual revenues of $30B, a $90B beer market represents a massive opportunity. The market size makes the beer market look attractive, but I’d like to understand if beer margins are typically high and determine how much market share Coca-Cola could realistically capture.
A second type of quantitative question you could be asked is to calculate profit or profitability. The interviewer may ask you:
Interviewer: Assume that a 12-ounce can of beer sells for $2 on average. To produce a keg of beer, it costs $100 for raw materials, $95 for labor, and $75 for storage. If a keg of beer holds 1,800 oz. of beer, what is the profit margin for beer?
Make sure you structure your approach and connect your answer to the case objective.
A sample answer could look like:
You: To calculate the profit margin for beer, I will first calculate the total costs to produce a keg of beer. Next, I will divide the volume of a keg by the volume of a can to determine how many cans a keg of beer produces.
Afterwards, I will divide the total cost of producing a keg of beer by the number of cans in a keg of beer to determine the cost per can.
Finally, I can use the price and cost per can of beer to calculate the margin of beer. Does this approach make sense to you?
You: Great. The total cost of a keg of beer is $100 plus $95 plus $75, or $270. The number of cans of beer in a keg is 1,800 oz. divided by 12 oz., or 150 cans.
Therefore, the cost per can of beer is $270 divided by 150 cans, or $1.80. Since the average price of beer is $2 per can, the profit is $0.20 per can. This makes the margin $0.20 divided by $2 or 10%.
Compared to Coca-Cola’s overall operating margin of 30%, the beer market profit margin of 10% is significantly lower. Although the market size for beer is large, the low margin makes the beer market less attractive.
A third type of quantitative question you could get asked is interpreting charts and graphs. The interviewer may show you the following:
![case study interview questions google Case interview chart and graph example](https://files.cdn.thinkific.com/file_uploads/163260/images/00b/ce5/68a/Case_interview_chart_and_graph_example.jpeg)
A helpful strategy is to start your analysis by explaining what the axes of the chart show. This will help you understand the chart better.
Next, don’t just read what numbers the chart shows, but interpret what those numbers mean for the case objective.
A sample answer might look like the following:
You: For this chart, we have market share on the y-axis and different categories of beer on the x-axis. For each category, we see that market share is concentrated among a few large players. This implies a highly competitive market with high barriers to entry. Because of this, the beer market does not look attractive because it is so competitive.
6. Answering qualitative questions
In addition to asking quantitative questions during the case interview, the interviewer will also ask qualitative questions.
One type of qualitative question you could get asked are brainstorming questions. For example, the interviewer might ask:
Interviewer: What are the barriers to entry in the beer market?
Most candidates answer by listing ideas that immediately come to mind:
- Brewing equipment
- Beer production expertise
- Distribution channels
This is a highly unstructured way of answering the question. Make sure to use a simple structure to organize your thoughts.
A simple structure, such as thinking about barriers to entry as either economic barriers or non-economic barriers, helps facilitate brainstorming and demonstrates logic and structure.
With this structure, you might come up with the following answer:
![case study interview questions google Case interview qualitative structure example](https://files.cdn.thinkific.com/file_uploads/163260/images/3a8/637/c2f/Case_interview_qualitative_structure_example.jpeg)
Have a simple structure when answering qualitative questions. Examples of other simple structures to use include the following:
![case study interview questions google Case interview qualitative frameworks](https://files.cdn.thinkific.com/file_uploads/163260/images/850/db6/c8c/Case_interview_qualitative_frameworks.jpeg)
Additionally, take your answer and connect it to the case objective. In this example, are these barriers to entry high or low? Do you think Coca-Cola can overcome these obstacles to enter the beer market?
You might answer this question in the following way:
You: I’m thinking of barriers to entry as economic barriers and non-economic barriers. Economic barriers include things such as equipment, raw material, and other capital. Non-economic barriers include: beer brewing expertise, brand name, and distribution channels.
Looking at these barriers, I think it will take Coca-Cola a lot of work to overcome these barriers. While Coca-Cola does have a brand name and distribution channels, they lack beer brewing expertise and would have to buy a lot of expensive equipment and machinery. These barriers make entering the beer market difficult.
Another type of question you could get asked are business opinion questions, such as the following:
Interviewer: Do you think there are significant production synergies in producing non-alcoholic beverages and producing beer?
As always, structure your answer and connect your answer to the case objective.
Here is a sample answer:
You: Production involves equipment, raw materials, and labor. There is likely some overlap in equipment, such as using the same bottling machines, but Coca-Cola will likely need new equipment for brewing beer.
Raw materials, on the other hand, are completely different. Coca-Cola will need to source barley, hops, and yeast, which it currently does not use in its existing beverages.
Finally, the same labor can be used, but employees will need new training since producing beer is fairly different from producing a non-alcoholic drink.
Overall, I think there are only a few production synergies that Coca-Cola can leverage, which makes entering the market a bit more difficult.
7. Delivering a recommendation
You’ve done a ton of work so far in the case interview and now it is time to put everything together into a recommendation.
Throughout the interview, you should have been making notes of key takeaways after each question you answer.
Take a look at the key takeaways you’ve accumulated so far and decide whether you want to recommend entering the beer market or not entering the beer market:
- The U.S. beer market size is $90B compared to Coca-Cola’s annual revenue of $30B
- The beer market profit margins are 10% compared to Coca-Cola’s average margin of 30%
- The beer market is highly concentrated across all categories
- Barriers to entry are moderate
- There are some synergies with existing production
There is no right or wrong recommendation, as long as you support your recommendation with reasons and evidence.
Regardless of what stance you take, make sure you have a firm recommendation. You do not want to be flimsy and switch back and forth between recommending entering the market and not entering the market.
Secondly, make sure your recommendation is clear and concise. Use the following structure:
- Clearly state what your recommendation is
- Follow that with the 2 - 3 reasons that support your recommendation
- State what potential next steps would be to further validate your recommendation
The conclusion of the case might look like the following:
Interviewer: Let’s say that you bump into the CEO of Coca-Cola in the elevator. He asks you what your preliminary recommendation is. What do you say?
You: I recommend that Coca-Cola should not enter the U.S. beer market for the following three reasons.
One, although the market size is fairly large at $90B, the margins for beer are just 10%, significantly less than Coca-Cola’s overall operating margin of 30%.
Two, the beer market is very competitive. In all beer segments, market share is concentrated among a few players, which implies high barriers to entry. Coca-Cola lacks beer brewing expertise to produce a great product that existing incumbents have.
Three, there are not that many production synergies that Coca-Cola can leverage with its existing products. Coca-Cola would need to buy new equipment, source new raw materials, and provide new training to employees, which will be time-consuming and costly.
For next steps, I want to look into Coca-Cola’s annual expected profits if they were to enter the U.S. beer market. I hypothesize that they will be unable to achieve an increase in annual profits of $2B within five years, but I’d like to confirm this through further analysis.
What are the different types of case interviews?
Case interviews cover a wide variety of functions and business situations. However, there are six common case interview business situations that account for the majority of all case interviews: profitability, market entry, growth, pricing, merger and acquisition, and new product.
There is a very high chance that you’ll see these types of case interviews in your first-round and final-round consulting interviews.
1. Profitability case interviews
Profitability cases ask you to identify why a company is experiencing a decline in profitability and what they should do to address it. This is the most common business situation for case interviews.
To solve these types of cases, you’ll need to understand quantitatively, what is the driver causing the decline in profits? You will need to determine whether revenues have gone down, costs have gone up, or both have occurred.
Afterwards, you’ll need to understand why this is happening. Once you understand this, you can brainstorm potential ideas and prioritize the solutions that are the most impactful and feasible to implement.
2. Market entry case interviews
Market entry cases ask you to determine whether a company should enter a new market. This is the second most common business situation for case interviews.
To make this decision, you’ll need to assess whether the market is attractive, how strong competitors are, whether your company has the capabilities to enter, and what the expected profitability is.
3. Growth case interviews
Growth cases ask you to determine how a company can best increase its revenues.
To solve this case, you’ll need to identify all of the major ways the company can grow.
Should the company grow organically by targeting new geographies or customer segments?
Should they grow by launching new products and services?
Instead, should the company grow inorganically by acquiring or forming a partnership with another company?
Once you have identified all of the major opportunities for growth, you can prioritize the opportunities that are the most impactful and feasible.
4. Pricing case interviews
Pricing cases ask you to determine how to set the optimal price on a product or service. To do this, you’ll need to consider different factors.
How much does the product cost to produce? You don’t want to price the product too low such that you have a loss on each sale.
How much are customers willing to pay for the product? You don’t want to price the product too high such that no customer is willing to purchase your product.
How much are competitors setting prices for similar products? You don’t want to price the product too high such that customers choose to purchase competitor products.
Considering each of these points will help you determine the right price to set.
5. Merger and acquisition case interviews
Merger and acquisition cases ask you to determine whether a particular company should be acquired.
To solve this case, you’ll first need to understand what the reason is for the acquisition. In most cases, the company will be looking to grow its revenues and profits.
Then, you’ll need to assess whether the market that the acquisition target plays in is attractive, whether the acquisition target itself is attractive, whether there will be any meaningful synergies, and whether the financials of the acquisition make sense.
These considerations will help you determine whether the acquisition should be made.
6. New product case interviews
New product cases ask you to determine whether a company should create and launch a particular new product.
To solve this case, you’ll need to assess whether the product’s market is attractive, whether the product meets customer needs, whether the product is superior to competitor products, whether the company has the capabilities to create and launch the product, and what the expected profitability is.
These considerations will help you make a smart and informed decision.
W hat are the different formats of case interviews?
There are three major formats of case interviews: traditional case interviews, written case interviews which assess presentation and communication skills more heavily and group case interviews which assess teamwork and collaboration more heavily.
1. Traditional Case Interview
The traditional case interview is the format that accounts for 80 to 90 percent of all case interviews. It is the format we have covered so far in which you and the interviewer work together to develop a recommendation or answer to a business problem.
The traditional case interview starts with the interviewer explaining the case background information to you. The case interview ends after you have delivered your recommendation to the interviewer.
There are two styles of traditional case interviews, candidate-led case interviews and interviewer-led case interviews.
- Candidate-led case interviews : You will be driving the direction of the case. You will propose what area of your framework to start in, what questions you would want to answer, what analyses you would want to do, and what the next step is to solve the case. If you go down the wrong direction, the interviewer will steer you back on course, but you ultimately decide what to do next.
- Interviewer-led case interviews : The interviewer will be steering and controlling the direction of the case. The interviewer will point you to which questions to answer, what analyses to do, and what the next step is to solve the case.
2. Written Case Interview
Written case interviews are much less common than traditional case interviews.
For written case interviews, you will be given a packet of information at the beginning of the interview. This packet usually has between 20 to 40 pages of graphs, charts, tables, and notes. You’ll be given information on the case background and the objective of the case.
In some written case interviews, you may also be given a list of important questions to answer. In other written case interviews, you’ll only be given the primary business problem you are asked to answer.
You’ll then have 1 to 2 hours to analyze the information packet and then make 3 to 5 slides to present your analysis and recommendation to the interviewer.
In some written case interviews, you’ll have to create these slides completely from scratch. In other written case interviews, you’ll have pre-filled slide templates that you will fill out with your analysis and work.
For written case interviews, you’ll be working by yourself. The interviewer will leave the room to let you work and then return when time is up to hear your presentation. During the presentation, the interviewer may ask follow-up questions on your work and findings.
3. Group Case Interview
Group case interviews are also much less common than traditional case interviews.
For group case interviews, you’ll be put into a group of 3 to 6 people with other candidates that are also interviewing for the same consulting job you are interviewing for. The group will be given materials which contain the case background, objective, and all of the information needed to solve the case.
You’ll then have 1 to 2 hours to work together as a group to create a slide presentation that summarizes your work and recommendation.
During this time, the interviewer will be listening in on the discussions and conversations that the group will have, but they will not interfere or answer any questions.
Once the time is up, your group will deliver your presentation to the interviewer, who may also ask follow-up questions on the work and findings.
For group case interviews, there is a heavy emphasis on assessing how well you work in a team. Consultants spend almost all of their time working closely in small teams, so teamwork and collaboration are essential.
Interviewers will assess you on criteria such as the following:
- Can you make meaningful contributions while working in a group?
- Are you easy to work with?
- Can you handle conflict and disagreement with teammates?
- Do you bring out the best ideas and qualities in other people?
How long does it take to prepare for case interviews?
Candidates typically spend 60 to 80 hours preparing for case interviews, equivalent to 6 to 8 weeks of preparation. However, exceptional candidates with strong business and communication skills might need as little as 4 weeks. Those lacking a business background could require as long as 12 weeks.
We have seen exceptional candidates pass their consulting interviews and receive offers from McKinsey, BCG, or Bain in just one or two weeks. We have also heard of candidates spending more than 100 hours preparing for case interviews, but receiving no consulting offers.
There are four factors that impact how much time you’ll need to dedicate to preparing for case interviews. Assessing these factors will help you set expectations for the amount of time you should expect to spend.
1. Natural intuition and ability
Case interviews require a strong business intuition and excellent communication skills. Some people will have a higher baseline on these skills than others.
If you have studied business in school or have worked a job that does similar work to consulting, you’ll likely already have a good business intuition. If you give speeches, presentations, or participate in debates frequently, you’ll likely already have good communication skills.
Although these abilities can be learned by anyone, some people will naturally have strong abilities to start with. For these people, they will likely need to spend less time preparing for case interviews than the average person.
2. Learning speed
Some people are faster learners than others. There are many skills you’ll need to learn and develop to be proficient in case interviews, such as structuring a framework, developing a hypothesis, solving math problems , and delivering a recommendation.
These skills require no specialized knowledge or expertise. Anyone can learn and master these skills with enough practice. However, some people will pick up these skills faster than others.
3. Quality of practice
The quality of your practice determines how quickly you can learn and master case interviews.
If you practice with case interview partners that don’t know how to properly deliver a case interview and provide feedback, you’ll learn much more slowly than someone practicing with a consultant who has given interviews before.
Similarly, if the practice cases you use are not representative of an actual case interview or don’t have outstanding model answers, you’ll learn much more slowly than someone using high-quality practice cases.
4. Consulting firm requirements
The amount of time needed to prepare for case interviews also depends on the consulting firms that you are applying for.
The top three consulting firms, McKinsey, BCG, and Bain, have the highest standards and requirements when assessing a candidate’s case interview capabilities. Less prestigious consulting firms may have a lower bar that you need to pass.
If you are recruiting for McKinsey, BCG, and Bain, you’ll likely need to spend more time preparing for case interviews than someone recruiting for Deloitte or Accenture.
When should I begin preparing for case interviews?
Given that it takes candidates on average 60 to 80 hours to prepare for case interviews, you should begin preparing for case interviews at least 6 to 8 weeks in advance. To give yourself adequate time, you should ideally start preparing 16 to 24 weeks in advance.
Preparing 16 to 24 weeks in advance provides sufficient buffer time. You may find yourself too busy to prepare for case interviews during some weeks. You may also realize that you have significant skill or capability gaps as you start preparing, requiring more time to improve.
Preparing for case interviews more than 24 weeks in advance should not be necessary.
Often times, candidates that start preparing too early will burn themselves out from having done too many practice cases. This often happens right before interviews begin, which leads to poor outcomes.
To avoid burning yourself out, start preparing for interviews ideally 16 to 24 weeks in advance and a minimum of 6 to 8 weeks in advance.
How do I prepare for case interviews?
There are seven steps to preparing for case interviews.
1. Understand what a case interview is
The first step in preparing for consulting case interviews is to understand exactly what case interviews are.
Case interviews are a special type of interview that every single consulting firm uses. They typically take 30 – 60 minutes and involve you working with the interviewer to solve a business problem and provide a recommendation.
When you are familiar with what case interviews are, it is important to know what a great case interview performance looks like.
Knowing what a great case interview performance looks like will facilitate how quickly you learn case interview strategies in the next step.
Before continuing onto the next step, you should be familiar with:
- The overall objective of a case interview
- The structure and flow of a case interview
- The types of questions you could get asked
- What a great case interview performance looks like
2. Learn the right strategies
Now that you have sufficient background knowledge, the next step in preparing for case interviews is to learn the right strategies to build good case interview habits.
It is much more effective to learn the right case strategies the first time than to learn poor strategies and try to correct them later.
The quickest, most efficient way to learn these strategies is to go through our Comprehensive Case Interview Course .
If you prefer reading case interview prep books instead, the three I recommend are:
- The Ultimate Case Interview Workbook
- Case Interview Secrets
Hacking the Case Interview provides strategies on exactly what to do and what to say in every step of the case interview. It is a concise and straight to the point guide. I recommend this book as the first book to read for beginners.
Case Interview Secrets teaches core concepts such as the issue tree , drill-down analysis, and a hypothesis driven approach. It illustrates these concepts through stories and anecdotes. If you have read Hacking the Case Interview, I recommend also reading this book to get perspectives from a second author. Check out our full review of Case Interview Secrets .
Case in Point provides a ton of specific and complex frameworks. However, you likely won’t be using many of these in an actual case interview because many of them are overly complex and specific. If you have time, it may be useful to skim through this book. Check out our full review of Case in Point .
At the bare minimum, read either the first or second book. If you have the time, read the first two books so that you can get strategies from two different authors.
Make sure to spend sufficient time learning the right strategies before starting to practice cases. It is ineffective to practice cases if you have no idea what strategies to practice and refine.
Before moving onto the next step, you should at least have strategies for the following parts of a case interview:
- Developing unique and tailored frameworks
- Solving quantitative problems
- Answering qualitative questions
- Delivering a recommendation
3. Practice 3-5 cases by yourself
Once you have learned the right strategies, the next step in case interview prep is to practice.
When practicing case interviews, it is usually better to practice with a case interview partner than to practice by yourself . Casing with a partner better simulates the real case interview experience.
However, when you are just starting to practice, I recommend doing the first 3 – 5 cases by yourself.
There are three reasons for this:
- You can get the hang of the case interview structure and format much more quickly working by yourself rather than having to wait to schedule a time with a partner
- There are many aspects of case interviews that you can practice without a partner, such as structuring a framework and solving quantitative problems. You can get much more practice working through these parts by yourself
- You may have difficulty finding a case interview partner if you are a complete beginner. Without having done any cases, you likely won’t know how to properly give a case or provide good feedback
4. Practice 5-10 cases with a partner
The next step in preparing for case interviews is to case with a partner.
Casing with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner.
When practicing cases with a partner, ensure you are spending enough time after cases to deliver feedback.
For a case that takes around 30 – 40 minutes, spend at least 15 – 20 minutes for feedback. Much of your learning and improvement will come from these feedback sessions.
Do not move onto the next step until you have done at least 5 – 10 cases and are beginning to feel comfortable with case interviews.
5. Practice with a former or current consultant
At this point, I highly recommend asking former or current consultants to give you a practice case. This will significantly help you prepare for case interviews.
Doing a mock case with a former or current consultant is highly advantageous because they know exactly how to run cases and give feedback. You’ll receive incredibly helpful feedback that your previous case partners likely missed.
If you feel that you are plateauing with your case partner, that is a sign you should do a mock case interview with a former or current consultant.
You can find former or current consultants among:
- People you met during the consulting recruiting process
- Your broader LinkedIn network
I would not ask a consultant that is involved with the consulting recruiting process for a case too prematurely. Although these practice cases are not evaluative, some firms will actually make note of how well you perform during the practice case.
At this point, you will have accumulated a long list of improvement areas from all of the different people you have cased with.
6. Work on your improvement areas
In this step of preparing for case interviews, you will work on strengthening and fine-tuning your improvement areas. Examples of common improvement areas include:
- Creating a more complete and mutually exclusive framework
- Performing math calculations quicker or more smoothly
- Providing more structure to your qualitative answers
- Leading the case more proactively
- Delivering a more succinct recommendation
Try to focus on improving one thing at a time. This is much more effective than trying to improve everything at once.
For some areas, such as math, it will be better to work independently. For other areas, such as learning to proactively lead the case, it will be better to work with a case partner.
If you are looking for more cases, look at the resources listed in step four. If you are looking for specific drills or practice problems for a particular part of a case interview, check out The Ultimate Case Interview Workbook .
Do not move onto the next step until you have finished working on all of your improvement areas.
7. Stay sharp
If you have progressed this far, congratulations! You have almost finished preparing for case interviews.
Once you feel that you have no more improvement areas to work on, the key is to not burn yourself out by doing too many unnecessary cases.
While each case that you do makes you slightly better, there is a point when doing too many cases can create case fatigue right before your interview. Case fatigue can negatively impact your interview performance.
On the other hand, you also don’t want to go weeks without having done a case. You may end up forgetting strategies or become rusty and slow.
Once you have achieved case mastery, I recommend doing no more than 2 cases per week in the weeks leading up to your interview. This ensures that you remain sharp for case interviews, but don’t have case fatigue.
What resources should I use to prepare for case interviews?

Case Interview Beginner Mistake #1: Lack of Structure
Failing to establish a clear framework for approaching the problem can lead to a scattered and unorganized response. It's important to outline a structured approach to solving the case.
Case Interview Beginner Mistake #2: Making Assumptions Without Clarification
Assuming information without seeking clarification can lead to incorrect conclusions. It's crucial to ask thoughtful questions to gather all necessary details.
Case Interview Beginner Mistake #3: Ignoring the Importance of Communication
Effective communication is key. Failing to articulate your thought process clearly or not actively engaging with the interviewer can hinder your performance.
Case Interview Beginner Mistake #4: Overlooking the Objective
Some candidates get so engrossed in solving the problem that they lose sight of the ultimate goal - providing actionable recommendations. Make sure your analysis leads to a clear conclusion.
Case Interview Beginner Mistake #5: Rushing Through the Case
Time management is crucial. Rushing through the case without taking the time to think critically about the problem can result in incomplete or inaccurate solutions.
Case Interview Beginner Mistake #6: Neglecting Quantitative Analysis
Many cases involve numerical data. Failing to perform thorough quantitative analysis or making calculation errors can be a significant setback.
Case Interview Beginner Mistake #7: Ignoring Alternative Perspectives
Tunnel vision can be detrimental. Failing to consider alternative viewpoints or approaches to the problem may lead to overlooking valuable insights.
Case Interview Beginner Mistake #8: Focusing Too Much on Memorized Frameworks
While frameworks are useful, relying too heavily on memorized approaches can lead to a superficial understanding of the case. It's important to adapt your framework to the specific context.
Case Interview Beginner Mistake #9: Neglecting to Check Assumptions
Sometimes, candidates make assumptions that are later proven to be incorrect. It's important to periodically revisit and validate your assumptions as you gather more information.
Case Interview Beginner Mistake #10: Lack of Practice and Preparation
Insufficient practice and preparation can lead to nervousness and poor performance during the actual interview. It's important to simulate case interview scenarios to build confidence and proficiency.
Case Interview Beginner Tip #1: Understand the Business Objective
The quickest way to fail a case interview is to answer or address the wrong business problem. Therefore, when the interviewer starts the case by reading the case background information, it is imperative that you identify what is the business problem and what is the primary question you are trying to answer. You should always verify the objective of the case with the interviewer.
Case Interview Beginner Tip #2: Ask Clarifying Questions
Don’t be afraid to ask clarifying questions. You will not be penalized for this. If there is a term that you are unfamiliar with, ask for the definition. If you don’t understand the objective of the case, ask questions to clarify this. If there is important information that you were not able to write down, ask the interviewer to repeat specific pieces of information.
All of these questions will help strengthen your understanding of the case situation and make it easier for you to solve the case.
Case Interview Beginner Tip #3: Don’t Use Memorized Frameworks
The issue with using memorized frameworks is that they aren’t tailored to the specific case that you are solving for. Many times, some of the elements of your memorized framework will not be relevant or important to the case. Additionally, interviewers can easily tell when you are regurgitating memorized information and not thinking critically.
Instead of memorizing frameworks, memorize a list of 8 – 10 broad business areas, such as the following:
- Competition
- Profitability
- Alternatives
When given a case, mentally run through this list and pick the 3 to 4 areas that are the most relevant to the case. If the list does not give you enough framework areas, brainstorm and add your own areas to your framework.
Case Interview Beginner Tip #4: Structure Your Math Approach
Before doing any math calculations, lay out an upfront approach or structure to walk the interviewer through what you are about to do. Developing a structure will help you avoid making unnecessary calculations or reaching a dead-end. If the interviewer approves of your approach, then the rest of the math problem is simple arithmetic.
Case Interview Beginner Tip #5: Use Abbreviations for Large Numbers
If you are working with large numbers in the thousands, millions, billions, or trillions, use abbreviations rather than writing out all of the zeroes.
For example, 10,000 can be expressed as 10K, 200,000,000 can be expressed as 200M, and 300,000,000,000 can be expressed as 300B. This reduces the chances that you’ll accidentally add or drop a zero in your numbers.
Case Interview Beginner Tip #6: Talk Through Calculations Out Loud
Talking through your calculations out loud provides two benefits. One, it decreases the likelihood that you’ll make a mistake. Two, it makes it easier for the interviewer to follow what you are doing. If you happen to get stuck or make a mistake, the interviewer can jump in to offer suggestions or guidance. The interviewer cannot do this if you are not communicating exactly what you are doing.
Case Interview Beginner Tip #7: Sense Check Your Numbers
Accidentally missing zeroes or adding extra zeroes during your case interview calculations is the most common math mistake. To avoid this, you can do a quick sense check after each calculation to confirm that your answer is the right order of magnitude.
For example, if you are multiplying 115 million by 22, you should expect your answer to be in the billions because 100 million * 20 = 2 billion.
Case Interview Beginner Tip #8: Talk Through The Axes of Charts and Graphs
When given charts or graphs to interpret, the very first thing you should do is to look at the axes. This is the most effective way to understand what the chart or graph is showing. When you are given multiple charts or graphs, this will also help you understand how each chart or graph relates to each other.
Case Interview Beginner Tip #9: Answer “So What?” After Every Question
When the interviewer asks you a quantitative or qualitative question during a case interview, don’t just answer it and stop there. After answering the question, ask yourself: “so what?” How does your answer help you solve the overall business problem? What implications does your answer have for your potential recommendation? You should be tying each answer that you give back to the case objective.
Case Interview Beginner Tip #10: Have a Firm Recommendation
You do not want to have a flimsy recommendation in which you switch back and forth between two different recommendations. Instead, have a recommendation that takes a firm stance. Remember that there is no right or wrong recommendation. As long as your recommendation is supported with data and evidence, your recommendation will be accepted.

What Is a Case Interview and How Do You Ace It? (+Examples)
6 min read · Updated on June 16, 2022
![case study interview questions google Lisa Tynan](https://s3.amazonaws.com/resume.cdn/articles/authors/93_931869_L.TynanBioProfilePic.jpg)
With case interviews being used more frequently for general consulting roles, it is essential to know how they work.
Unless you've interviewed for a management consultant or investment banking job, chances are you haven't experienced a case interview. However, this rather unique interview process is slowly becoming the norm for a wider variety of management consulting roles.
That's why you should know what to expect and how to handle it professionally.
What is a case interview?
A case interview is defined as “a hypothetical business situation that is presented during the job interview process to determine how a candidate thinks about a particular problem and how they would solve it.”
Usually, this specific business problem or situation is one that a candidate would face if hired for the job in that specific company. For example, a candidate's prompt might be determining whether there's a market for home-use ultraviolet sterilizers. They could begin by asking about the target market, the cost of each unit, and how they'll be sold. As they get into it, they may offer ideas on how to create more markets, like making the units in different sizes or for specific items like phones.
The overall goal is to assess how the candidate as a consultant thinks about and arrives at particular solutions or answers for a specific business problem scenario.
How is a case interview structure different from other interview formats?
As with a regular or competency-based interview format, the traditional case interview seeks to assess a candidate's skills coupled with how they operate in a specific hypothetical business situation. However, that is where most of the similarities end.
Rather than talking about how you handled something in a past or present job, a case interview presents a particular situation and asks you to work with it right there in the job interview.
Answers for case interview questions can be verbal or written and often include the creation of charts, graphs, or illustrations to make your point. What's more, case interview questions may also feature brain teasers or other analytical tasks that are not related to the company or the job. Also, unlike a regular interview, it's acceptable and expected that the candidate interacts with and asks questions of the interviewer as part of the problem-solving process.
But, perhaps the biggest difference is that there's no one “right” or correct answer to the questions or scenarios because there is often more than one acceptable way to handle the hypothetical situation. In fact, interviewers are looking for ingenuity and that “out-of-the-box” thinking strategy.
To sum up, it's just as much about the process as the solution.
Which businesses benefit from case interviews?
In general, case interviews work best for consulting firms, but most companies can benefit from determining whether or not a candidate can effectively size up and handle real-life business situations. Not only does it demonstrate a person's problem-solving skills and analytical abilities, but it also shows their willingness to get more information by asking questions.
Essentially, interviewers are watching as candidates figure out what they're looking for, what analysis they want to use, and what insights and theories they develop as they move toward a data-driven, quantifiable solution. These interviewers are also looking for strong interpersonal abilities and communication skills — management consultants must deal with people as well as data after all.
Are there specific case interview formats?
There are a few basic formats used in case interviews.
Candidate-led scenarios
In candidate led case interviews, the candidate is required to lead the discussion and development of the case. You'll be evaluated on developing and evaluating your theory while simultaneously formulating and answering the relevant questions needed.
You don't have to work from beginning to end but are able to move among and focus on different aspects of the case as you solve it.
Interviewer-led scenarios
In interviewer-led case interviews, these interviews have a preset format where the interviewer directs the focus, tempo, and sequence of the problem-solving process, with candidates solving the case from beginning to end. Each problem has predetermined questions, and you may or may not be given data to work with.
The approach and evaluation parameters are the same as the candidate-led interview.
Group scenarios
In a group case interview, here you work with a team of other candidates to analyze the case, collaborating to come up with solutions.
Presentation-only scenario
You have two hours by yourself to review data, create a premise, build an issue tree, and analyze your results. You then present this to the interviewer, who will question and challenge your data just like a client would to see how you defend your results.
Case interview sample questions
There really are no “typical” case interview questions; rather, you're presented with a situation or business problem and asked to handle it.
Here's a case interview question example.
“Our client is a five-million-dollar manufacturer of eye-glass frames whose sales have dropped markedly in the past 3 years. What should they do?”
If your interviewer utters the words “Our client…”, you know you're in a case interview.
How to prepare for a case interview
Case interview prep is the key to success. Luckily, there are only a few case interview “types” that are regularly used, and your job is to know and study them. They are:
New product development
Pricing strategies
Entering a new market space
Growth strategies
Starting a new business
Improving profitability/increasing sales/reducing costs
Acquiring a company
Create your own situations around these case interview examples, practicing your answers alone or with a buddy. You can also look up actual examples of these cases, review the analysis, and come up with your own unique solutions.
Preparation and practice will make the actual case interview much less daunting and allow you to feel more confident. The more you can actually relax and have fun in a case interview, the more likely you are to enjoy the actual work — and get hired to do it.
Don't have a friend to practice with? Need more of a push? Our interview coaches can help.

Case Study Interview Questions About the Customer's Business
Knowing the customer's business is an excellent way of setting the tone for a case study.
Use these questions to get some background information about the company and its business goals. This information can be used to introduce the business at the beginning of the case study — plus, future prospects might resonate with their stories and become leads for you.
- Would you give me a quick overview of [company]? This is an opportunity for the client to describe their business in their own words. You'll get useful background information and it's an easy prompt to get the client talking.
- Can you describe your role? This will give you a better idea of the responsibilities they are subject to.
- How do your role and team fit into the company and its goals? Knowing how the team functions to achieve company goals will help you formulate how your solution involves all stakeholders.
- How long has your company been in business? Getting this information will help the reader gauge if pain points are specific to a startup or new company vs. a veteran company.
- How many employees do you have? Another great descriptor for readers to have. They can compare the featured company size with their own.
- Is your company revenue available? If so, what is it? This will give your readers background information on the featured company's gross sales.
- Who is your target customer? Knowing who the target audience is will help you provide a better overview of their market for your case study readers.
- How does our product help your team or company achieve its objectives? This is one of the most important questions because it is the basis of the case study. Get specifics on how your product provided a solution for your client. You want to be able to say "X company implemented our solution and achieved Y. "
- How are our companies aligned (mission, strategy, culture, etc.)? If any attributes of your company's mission or culture appealed to the client, call it out.
How many people are on your team? What are their roles? This will help describe key players within the organization and their impact on the implementation of your solution.
![case study interview questions google case-study-questions_5](https://www.hubspot.com/hs-fs/hubfs/case-study-questions_5.webp?width=1124&height=598&name=case-study-questions_5.webp)
Case Study Interview Questions About the Environment Before the Purchase
A good case study is designed to build trust. Ask clients to describe the tools and processes they used before your product or service. These kinds of case study questions will highlight the business' need they had to fulfill and appeal to future clients.
- What was your team's process prior to using our product? This will give the reader a baseline to compare the results for your company's product.
- Were there any costs associated with the process prior to using our product? Was it more expensive? Was it worth the cost? How did the product affect the client's bottom line? This will be a useful metric to disclose if your company saved the client money or was more cost-efficient.
- What were the major pain points of your process prior to using our product? Describe these obstacles in detail. You want the reader to get as much information on the problem as possible as it sets up the reasoning for why your company's solution was implemented.
- Did our product replace a similar tool or is this the first time your team is using a product like this? Were they using a similar product? If so, having this information may give readers a reason to choose your brand over the competition.

Getting answers to this question will illustrate to readers the client's concerns about switching to your service. Your readers may have similar concerns and reading how your client worked through this process will be helpful.
- Why didn't you buy our product or a similar product earlier? Have the client describe any hesitations they had using your product. Their concerns may be relatable to potential leads.
- Were there any "dealbreakers" involved in your decision to become a customer? Describing how your company was able to provide a solution that worked within those parameters demonstrates how accommodating your brand is and how you put the customer first. It's also great to illustrate any unique challenges the client had. This better explains their situation to the reader.
- Did you have to make any changes you weren't anticipating once you became a customer? Readers of your case study can learn how switching to your product came with some unexpected changes (good or bad) and how they navigated them. If you helped your client with troubleshooting, ask them to explain that here.
How has your perception of the product changed since you've become a customer? Get the interviewee to describe how your product changed how they do business. This includes how your product accomplished what they previously thought was impossible.

The answers to these questions will help potential customers through their decision-making process.

Case Study Interview Questions About the Buying Team and Internal Advocates
See if there are any individuals at the customer's company who are advocates for your product.
- Are there any additional team members you consider to be advocates for our product? For example, does anyone stick out as a "power user" or product expert on your team? You may want to interview and include these power users in your case study as well. Consider asking them for tips on using your service or product.
- Is there anyone else on your team you think we should talk to? Again, the more people can share their experience using your product, the better.

Before you can start putting together your case study, you need to ask your customer's permission.
If you have a customer who's seen success with your product, reach out to them. Use this template to get started:
Thank you & quick request
Hi [customer name],
Thanks again for your business — working with you to [solve X, launch Y, take advantage of Z opportunity] has been extremely rewarding, and I'm looking forward to more collaboration in the future.
[Name of your company] is building a library of case studies to include on our site. We're looking for successful companies using [product] to solve interesting challenges, and your team immediately came to mind. Are you open to [customer company name] being featured?
It should be a lightweight process — [I, a product marketer] will ask you roughly [10, 15, 20] questions via email or phone about your experience and results. This case study will include a blurb about your company and a link to your homepage (which hopefully will make your SEO team happy!)
In any case, thank you again for the chance to work with you, and I hope you have a great week.
[Your name]
If one of your customers has recently passed along some praise (to you, their account manager, your boss; on an online forum; to another potential customer; etc.), then send them a version of this email:
Hey [customer name],
Thanks for the great feedback — I'm really glad to hear [product] is working well for you and that [customer company name] is getting the results you're looking for.
My team is actually in the process of building out our library of case studies, and I'd love to include your story. Happy to provide more details if you're potentially interested.
Either way, thank you again, and I look forward to getting more updates on your progress.
You can also find potential case study customers by usage or product data. For instance, maybe you see a company you sold to 10 months ago just bought eight more seats or upgraded to a new tier. Clearly, they're happy with the solution. Try this template:
I saw you just [invested in our X product; added Y more users; achieved Z product milestone]. Congratulations! I'd love to share your story using [product] with the world -- I think it's a great example of how our product + a dedicated team and a good strategy can achieve awesome results.
Are you open to being featured? If so, I'll send along more details.
Case Study Benefits
- Case studies are a form of customer advocacy.
- Case studies provide a joint-promotion opportunity.
- Case studies are easily sharable.
- Case studies build rapport with your customers.
- Case studies are less opinionated than customer reviews.
1. Case studies are a form of customer advocacy.
If you haven't noticed, customers aren't always quick to trust a brand's advertisements and sales strategies.
With every other brand claiming to be the best in the business, it's hard to sort exaggeration from reality.
This is the most important reason why case studies are effective. They are testimonials from your customers of your service. If someone is considering your business, a case study is a much more convincing piece of marketing or sales material than traditional advertising.
2. Case studies provide a joint-promotion opportunity.
Your business isn't the only one that benefits from a case study. Customers participating in case studies benefit, too.
Think about it. Case studies are free advertisements for your customers, not to mention the SEO factor, too. While they're not promoting their products or services, they're still getting the word out about their business. And, the case study highlights how successful their business is — showing interested leads that they're on the up and up.
3. Case studies are easily sharable.
No matter your role on the sales team, case studies are great to have on hand. You can easily share them with leads, prospects, and clients.
Whether you embed them on your website or save them as a PDF, you can simply send a link to share your case study with others. They can share that link with their peers and colleagues, and so on.
Case studies can also be useful during a sales pitch. In sales, timing is everything. If a customer is explaining a problem that was solved and discussed in your case study, you can quickly find the document and share it with them.
4. Case studies build rapport with your customers.
While case studies are very useful, they do require some back and forth with your customers to obtain the exact feedback you're looking for.
Even though time is involved, the good news is this builds rapport with your most loyal customers. You get to know them on a personal level, and they'll become more than just your most valuable clients.
And, the better the rapport you have with them, the more likely they'll be to recommend your business, products, or services to others.
5. Case studies are less opinionated than customer reviews.
Data is the difference between a case study and a review. Customer reviews are typically based on the customer's opinion of your brand. While they might write a glowing review, it's completely subjective and there's rarely empirical evidence supporting their claim.
Case studies, on the other hand, are more data-driven. While they'll still talk about how great your brand is, they support this claim with quantitative data that's relevant to the reader. It's hard to argue with data.
An effective case study must be genuine and credible. Your case study should explain why certain customers are the right fit for your business and how your company can help meet their specific needs. That way, someone in a similar situation can use your case study as a testimonial for why they should choose your business.
Use the case study questions above to create an ideal customer case study questionnaire. By asking your customers the right questions, you can obtain valuable feedback that can be shared with potential leads and convert them into loyal customers.

What are the most common case study interview questions at McKinsey, BCG and Bain?
If you’re preparing to interview at a top management consulting firm like McKinsey, BCG or Bain (MBB), you might be wondering what kind of questions you can expect to receive in your case interviews .
In this article we take a look at the most common types of case questions asked by interviewers at the world’s top-3 consulting firms. We also consider how you can develop the skill of structuring answers to case questions.
The 10 most common case interview questions
To identify the most common case interview questions posed by interviewers at McKinsey, BCG and Bain, we surveyed CaseCoach users who interviewed at one of the firms for a generalist role in 2023. We found that 90% of the 260+ case interviews reported by respondents fell into one of 10 question types:
Profit improvement | ||
Revenue growth | ||
Market entry | ||
Cost cutting | ||
Process optimization | ||
Product launch | ||
Mergers and acquisitions | ||
Investment decision | ||
Response to a competitive threat | ||
Pricing | ||
Other |
The respondents in our study all interviewed for generalist consulting positions at McKinsey, BCG and Bain. It’s no coincidence that the case interview questions that they were asked align to the typical challenges and opportunities faced by CEOs.
However, it’s important to bear in mind that this is not an exhaustive list. If you’re interviewing for a practice-focused role on the firms’ expert career track you may be given cases that focus on your area of specialization, rather than the topics in our list.
Your target firm and location may also have a bearing on the type of cases you are given. This is because MBB offices tend to use the work they have done for clients to develop their case questions for candidates.
Knowing the frameworks that correspond to these questions is critical
As a management consulting candidate, it’s vital that you have an understanding of the issues behind the most common case questions and know the frameworks for tackling them inside out.
In our Interview Prep Course, we provide detailed examples of how to structure these questions at the beginning of a case interview. We also explain how different circumstances should influence your approach.
You can learn more about structuring frameworks for specific types of cases in our articles on mastering profitability questions , answering revenue growth questions and nailing market sizing question s.
You can also find examples of the following types of cases in our Case Library :
- Profit improvement
- Market entry
- Mergers and acquisitions
- Response to a competitive threat
If you’re not a CaseCoach subscriber, you can gain access to these examples by signing up for a free account.
You must be able to create custom approaches to answering case study interview questions
When it comes to answering a case question effectively, applying a framework in a ‘cookie-cutter’ fashion simply won’t allow you to give the best possible answer or impress your interviewer with your structuring skills.
In fact, respondents in our survey reported that many of the cases they received could be assigned to several case types and could not be solved by applying an off-the-shelf framework. A profitability question may have a focus on market growth or launching a product, for example. To structure a response to this kind of question, candidates need to combine several frameworks and use them as building blocks for creating their answer.
Even common questions require a custom approach: a profitability question that relates to a chain of restaurants, for example, will naturally require a different approach to a question on the same topic in the manufacturing industry.
Interviewers want to understand how your mind works and to see you think on your feet. Increasingly, they are using non-traditional cases (such as those set in the public sector) to test this. Ten percent of the respondents in our survey couldn’t assign the questions they had faced to a particular case type, suggesting that they were given an unusual problem to solve.
As a candidate, you’ll need to demonstrate that you are capable of proposing a custom structure to any case question, rather than simply relying on a framework.
What does a good custom structure look like?
An effective structure should focus on the right question and then break it down into an exhaustive set of independent drivers. The structure should also provide an approach to solving the case and supply helpful insights. In other words, it should pass ‘the AIM test’:
- Answer-focused: a strong case structure will be focused on the right question and will provide an approach to solving the case.
- Insightful: the structure should be tailored to the specific situation posed by the case question and should provide helpful insights.
- MECE: this stands for ‘mutually exclusive and collectively exhaustive’. A good MECE structure will break the question down into an exhaustive set of independent drivers that neither overlap nor omit anything important.
You should use the AIM test as a guide for structuring your answers to case questions. If your structure meets all the criteria, it should provide a strong foundation upon which to solve the case. You can learn more in our article on case structuring and how to do it effectively .
![](http://sektorel.online/777/templates/cheerup/res/banner1.gif)
Structuring skills take time and practice to develop
Building the muscle required to structure answers to a wide range of case questions, combine frameworks and develop your own approach to solving non-traditional cases takes a great deal of preparation.
First, you need to build an inventory of frameworks that you can use as building blocks to develop custom structures. You can do this by watching the structuring lectures in our Interview Prep Course , which covers topics such as the AIM test, business and academic frameworks, and using logical approaches to craft bespoke structures for unusual cases.
You then need to gain exposure to a variety of cases. You can choose from the 100+ questions in our Case Library and then schedule a practice session with a partner from our diverse community of top candidates in our Practice Room .
Structuring is one of the case interview skills you can practice alone in addition to practicing with a partner. Our Interview Prep Course includes 60+ structuring drills – which provide multiple solutions to each problem – to help you do this.

How to Conduct a High-Value Case Study Interview (And 4 Mistakes To Avoid)
![case study interview questions google How To Conduct A High-Value Case Study Interview (And 4 Mistakes To Avoid)](https://breadcrumbs.io/wp-content/uploads/2021/01/case-study-5-768x402.png)
Let’s talk about case study interviews.
Case studies allow brands to demonstrate exactly how they can help resolve specific pain points, how customers are using their products or tools, and an exact example of what kind of results people can expect.
This is important because plenty of businesses make big claims, trying to outshine their competition. There isn’t a marketing agency out there that won’t promise to get you more reach or a law firm that doesn’t like to appear confident in their ability to win cases.
Every brand will proclaim that they can best solve their customer’s needs, but those claims on their own rarely mean much. They want to know that you can live up to what you promise, and seeing case studies from existing clients can win them over.
To create high-value case studies that can help you attract and convert customers, it only makes sense that you’ll need to start with a killer interview.
In this post, we’re going to look at how to conduct a case study interview that will help you create high-value case studies to draw attention and quality leads to your business.
Why Interviewing Clients Directly for Case Studies Is So Important
We’re all busy, so it can be tempting to put off case studies or relegate the case study interviews to a quick Google form that asks specific questions.
While you can create basic case studies off of this information, especially if you only want to showcase quick results, it won’t be nearly as impactful as case studies created off of more in-depth interviews.
These interviews can take place by email, phone, Zoom, or in person, but the idea is that there is plenty of room for open discussion. Actual interviews can help you go beyond basic information so that you can get to the story and the pain points of how your clients have been impacted.
There’s also a great chance that they’ll share more during an open conversation that can be a crucial component to the case study that they may not have thought to share on a form because you may not have thought to ask.
Strong case study interviews are an essential part of creating dynamic, engaging content that can actually convince your target audience that you’re the right business to purchase from.
How to Prepare for Case Study Interviews
Conducting a rocking case study interview all comes down to great preparation, so let’s take a look at how to do exactly this.
Think About Your Target Audience’s Pain Points
Before you start formulating your case study interview questions, you want to think about what you want your case studies to convey.
Case studies allow you to go beyond sharing simple results (which are powerful enough on their own and should still be an important part of the content), allowing you to dive into more nuance to address the pain points of potential leads fully.
For example, a virtual phone line company may want to consider going beyond stressing their 99% service uptimes and touch on additional features they offer. Emphasizing that offer call scheduling to give business owners more of their time back on an automated basis, for example.
This case study from AdEspresso is an excellent example of what to look at when considering your audience’s pain points. There’s a client who ran highly seasonal campaigns who didn’t want to leverage discounts to drive sales to keep it fair for pre-order customers. It discusses her specific challenges and pain points and addresses the overall solution instead of simply listing results.
![case study interview questions google Case Study Interview: Adespresso](https://breadcrumbs.io/wp-content/uploads/2021/01/Screen-Shot-2021-01-13-at-3.20.35-PM-1024x723.png)
As pain points can be a crucial part of writing compelling case studies , break down your audience’s niches and different needs that they may have. You can ask your interviewee questions that can help you tap into the pain points for the case study. We’ll look at specific questions for how to tackle this in a moment.
Expect Interviewee Objections
When you first reach out to a potential case study subject and start discussing the idea of featuring their brand, know that you may encounter objections from the subject themselves.
They may be alright with you using some part of their story, strategy, or results while still being concerned about protecting their own or their business’s privacy.
As a content marketer, for example, I know exactly how many of my posts are performing across some of my client sites, how much they drive in revenue, how much traffic they’re getting, and what’s bringing them there.
A client may be okay with me talking about working with them or sharing samples but might be less than thrilled about me divulging information about their specific site pattern trends, the custom-for-them strategy we used, or their revenue. For example, the case study from SEMRush below is extremel y specific; not all clients may be comfortable with this.
![case study interview questions google Case Study Interview: Semrush](https://breadcrumbs.io/wp-content/uploads/2021/01/Screen-Shot-2021-01-13-at-6.29.30-PM-1024x437.png)
Be prepared for this before you reach out, and consider what you can do to accommodate requests. These objections may arise before the case study interview, but they may pop up during as well.
Here are a few examples of common workarounds:
- Instead of saying that my post for Bob’s Blog helped the site go from $100 in revenue to $200, I can say that it doubled the revenue or doubled conversion rates (whatever is accurate).
- Maybe I can share the general strategy I used for Bob’s blog without actually naming them and omitting key identifying details, like the keywords used.
- They may be alright with you sharing the detailed strategy and general results (2x conversion rate instead of 5.6% conversion rate) and the brand name , OR they may only be okay with sharing their story and results.
Each client is different and comfortable with sharing different information. While it is typically most beneficial to be able to name the client’s brand name, if this isn’t an option consider settling for a more specific industry tag like “a client in the women’s sustainable fashion industry” instead.
Watch what our customers say
“Life before Breadcrumbs was, I think you could call it the Dark Ages. We started with an SLA of two days to a week sometimes. And we’re getting within the 10 to 5-minute mark. So that’s so exciting for us.”

Ready Your Case Study Interview Questions
After you’ve thought about potential objections and any key notes you really want to focus on with your case study, you can put together your case study interview questions.
We’ll discuss specific case study interview questions and templates a bit later on, but prepare these in advance. Ideally, research each individual case study subject in advance and try to ask questions that will be relevant to them.
This is important- write your questions down, even if you’ll be having a phone call. Organize them with the natural progression you expect the call or conversation to take so you don’t lose your train of thought, and check back before the call is over to make sure you’ve asked everything you need to.
At the end of the interview, ask if there’s anything else they’d like to share. Don’t forget this: some of the best parts of case studies can surprise the interviewer at the time!
Look for a Story
When you’re putting together your questions and interviewing the case study subject, keep your eyes open for a “story.”
Stories don’t have to be long and complex; they should center your brand whenever possible.
If your automation software helps a business owner save time, that’s an appealing benefit. But if they’re happy to share that it meant that they could put more time into expanding their business or that they could be at home more with their newborn child, that takes a simple fact and makes it more emotionally compelling.
You can build an entire case study around a great story, and you can see exactly how effective this is with the headline of this case study from Freshbooks , reading “How Freshbooks Helped Marc Keep His New Year’s Resolution.

4 Case Study Interview Mistakes to Avoid
When you’re preparing for and conducting case study interviews, there are a few common mistakes that you’ll want to avoid. These can cause you to miss out on potential interviews or lessen the impact of the interviews themselves.
Make sure to avoid the following mistakes:
- Using a single form that’s emailed to case study subjects. Whenever possible, back-and-forth conversations can typically yield much more dynamic case studies. While some clients may firmly want to stick to email, try to opt for zoom calls or at least several emails if you can.
- Not being clear on what information you can use in the case study. Make sure they know that you’ll publish it on your site, and get their permission in writing (email is fine!) to feature them and their results. It’s considered a good practice to let the client review the case study before you publish it if they’re concerned.
- Trying to shoehorn a client into a predetermined story. I once worked with another content writer on a case study project, and during the interview, it was so clear they were trying to fit a subject’s experience into this perfect story the writer had concocted. This typically doesn’t work, however, and it can prevent you from finding the great and unique parts of each individual’s story and success. Go in with an open mind if you can.
- Skipping small talk. If you go in all-business, the case study subject may be more likely to answer only what’s asked. When you start on the basis of enjoying the conversation, however, they’ll share more, and that can be where the magic happens.

Case Study Interview Examples: What This May Look Like
Need a case study interview template with plenty of questions to draw inspiration from? What you ask will vary depending on your industry, your client, and the type of case study you want to create, but there are some set questions you should ask across the board.
It’s good to break these down into different sections while asking open-ended questions so that there’s plenty of room for the subject to share more.
Start by asking about the brand with questions like the following:
- “Can you tell me about your brand and what you do?”
- “Is there anything you’d like us to make sure our readers know about your brand?”
Then move on to asking about how they use the product and their challenges. Some case study interview questions for this may include:
- “Why did you decide to use our brand/product/service? What feature made you choose us?”
- “What pain points and challenges did you have before coming to us?”
- “Have you tried other solutions before? If so, why did you decide to come to us?”
Next, focus on process and results:
- “Can you tell us how you’ve used our product/service and how it’s helped your business?”
- “What results did you get? Did it speed up your team/improve efficiency/drive more results/improve health/ insert use case here?”
- How long were you able to maintain these results, and how did the results help you?
Final Thoughts
A case study interview can seem like a daunting task, but with a little bit of research ahead of time, it can be a smooth process that can yield exceptional information for outstanding case studies. Remember that case studies can only be as strong as the information you have, so the importance of a great interview can’t be overstated.
For best results, take a look at a few case studies online that you liked as a customer, and think about what you’d need to ask in order to get that information. That can help you cover your bases and ensure that you’re asking everything you need to.

BCG: Tips And Case Interview Examples
The Boston Consulting Group website states something very important: the goal of the hiring process is to get to know you better, which means, in the context of Consulting interviews, understanding how you solve problems .

I have sorted this list of 253 case studies by type: profitability, market expansion, industry analysis, pricing, investment or acquisition, and guesstimates (also known as market sizing questions).
![case study interview questions google Full list of case study examples sorted by type](https://careerinconsulting.com/wp-content/uploads/2019/12/Full-list-of-case-studies-sorted-by-type-1024x549.png)
Bonus #1: Know The Types Of Cases You Are Likely To have During Your Interviews
- Profitability cases (29% of cases from that list)
- Investment cases (19% of cases from that list)
- Market sizing questions (15% of cases from that list)
As a result, assuming you’ll have 6 interviews (and therefore 6 case interviews) during the recruitment process:
- “Profitability cases are 29%” means that chances to have 2 profitability case studies during your recruitment process are very high
- “Investment cases are 19%” means that chances to have 1 investment case study during your recruitment process are very high.
- “ Guesstimates are 15%” means that chances of having 1 market sizing question during your recruitment process are high.
Bonus #2: The 10 Cases I Recommend You Doing Now
Over 250 examples of case interviews are a great list, and you may not know where to start.
So, I’ve compiled a list of my 10 favorite case studies.
The 5 case studies I recommend doing if you are a BEGINNER
1. stern case book: drinks gone flat (starting at page 24).
This is a good introduction to a common type of case (declining sales here). I liked the solution presented for this case, particularly how it started by isolating declining sales (what range of products? Volumes or prices, or both?).
2. Stern case book: Sport bar (starting at page 46)
This is an investment case (should you invest in a new bar). Even if the solution presented in this case book is not MECE , it covers the most common quantitative questions you might have in such a case. I recommend doing this case.
3. Stern case book: MJ Wineries (starting at page 85)
This is a profitability case. I liked the solution presented in this case because it illustrates how specific good candidates should be. The case concerns wine, so a good candidate should mention the quality of lands and grapes as important factors.
4. AGSM case book: Piano tuners (starting at page 57)
This is a typical market sizing question. How to answer this type of question is a must-know before going to your interviews.
5. Darden case book: National Logistics (starting at page 49)
Again, this is a very common case (how to reduce costs). I liked the broad range of questions asked in this case, covering key skills assessed by consulting firms during case interviews: brainstorming skills (or creativity), quantitative skills, and business sense.
The 5 case studies I recommend if you are more ADVANCED in your preparation
1. stern: the pricing games (starting at page 55).
This case study asks you to help your client assess different business models. I liked this case because the range of issues to tackle is quite broad.
2. Wharton 2017: Engineer attrition at SLS Oil & Gas Services (starting at page 55)
I liked this case study because the case prompt is uncommon: your client has been facing a very high attrition rate among its population of Engineers. As a result, it’s very unlikely that your solution fits a well-known framework, and you’ll have to demonstrate your problem-solving skills by developing a specific solution.
3. Wharton 2017: Pharma Company Goes International, Outsources Benefits, Integrates New Technology (starting at page 95)
This case is about a client considering outsourcing a part of their activity. Even though I don’t know if this type of case study is very common, I had many case studies like this when I passed my interviews a few years ago. And I always found them difficult!
4. Insead: Gas retail case (starting at page 73)
The question in the problem statement is very broad, making this case difficult. So, only good candidates can have a structured case discussion here.
5. Darden: Fire Proof (starting at page 84)
This is a market entry case. Try to solve it by developing a structure as MECE as possible.

Practice with experts
Using case interview examples is a key part of your interview preparation, but it isn’t enough.
At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.
If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.
Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

If you don’t want to spend hours searching the web, this article presents a comprehensive and convenient list for you – with 35 example cases, 16 case books, along with a case video accompanied by detailed feedback on tips and techniques.
A clear understanding of “what is a case interview” is essential for effective use of these examples. I suggest reading our Case Interview 101 guide, if you haven’t done so.

What should I know about McKinsey Case interviews?
At McKinsey, case interviews often follow the interviewer-led format , where the interviewer asks you multiple questions for you to answer with short pitches.
How do you nail these cases? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!
For a detailed guide on interviewer-led cases, check out our article on McKinsey Case Interview .

What should I know about BCG & Bain case interviews?
Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.
The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.
Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation.

What should I know about Deloitte case interviews?
Case interviews at Deloitte also lean towards the candidate-led format like BCG and Bain.
The Deloitte consultant recruitment process also features group case interviews , which not only test analytical skills but also place a great deal on interpersonal handling.
Accenture case interview examples
Accenture divides its cases into three types with very cool-sounding names.
Sorted in descending order of popularity, they are:
These are similar to candidate-led cases at Bain and BCG. albeit shorter – the key is to develop a suitable framework and ask the right questions to extract data from the interviewer.
These are similar to the market-sizing and guesstimate questions asked in interviewer-led cases – demonstrate your calculations in structured, clear-cut, logical steps and you’ll nail the case.
These cases have you sort through a deluge of data to draw solutions; however, this type of case is rare.
Capital One case interview examples
Capital One is the odd one on this list – it is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones.
Having gone through Capital One’s guide to its cases, I can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers.
Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!
See Capital One Business Analyst Case Interview for an example case and answers.

Case interview example – Case video
The limitation of most official case interview examples is that they are either too short and vague, or in text format, or both.
To solve that problem for you, we’ve extracted a 30-minute-long, feedback-rich case sample from our Case Interview End-to-End Secrets Program .
This is a candidate-led, profitability case on an internet music broadcasting company called Pandora.
In 30 minutes, this candidate demonstrates the exact kind of shortcoming that most candidates suffer during real case interviews – they come in with sharp business senses, then hurt their own chances with inadequate techniques.
Here are seven notable areas where the candidate (and you) can improve:
Thanking Throughout the case, as especially in the opening, he should have shown more appreciation for the time the interviewer spent with him.
Structured opening The candidate’s opening of the case feels unstructured. He could have improved it by not mixing the playback and clarification parts. You can learn to nail the case in a 3-minute start through this video on How to Open Any Case Perfectly .
Explicitness A lot of the candidate’s thought process remains in his head; in a case interview, it’s better to be as explicit as possible – draw your issue tree out and point to it as you speak; state your hypothesis when you move into a branch; when you receive data, acknowledge it out loud.
Avoiding silence The silence in his case performance is too long, including his timeout and various gaps in his speech; either ask for timeout (and keep it as short as possible) or think out loud to fill those gaps.
Proactivity The candidate relies too much on the interviewer (e.g: asking for data when it can easily be calculated); you don’t want to appear lazy before your interviewer, so avoid this.
Avoiding repeating mistakes Making one mistake twice is a big no-no in consulting interviews; one key part of the consulting skill set is the ability to learn, and repeating your mistakes (especially if the interviewer has pointed it out) makes you look like someone who doesn’t learn.
Note-taking Given the mistakes this candidate makes, he’s probably not taking his notes well. I can show you how to get it right if you watch this video on Case Interview Note-Taking .
Nonetheless, there are three good points you can learn from the candidate:
The candidate sums up what he’s covered and announces his upcoming approach at the start and at key points in the case – this is a very good habit that gives you a sense of direction and shows that you’re an organized person.
The candidate performs a “reality check” on whether his actions match the issue tree; in a case interview it’s easy to lose track of what you’re doing, so remember to do this every once in a while.
The candidate prompts the interviewer to give out more data than he asked for; if anything, this actually matches a habit of real consultants, and if you’re lucky, your interviewer may actually give out important pieces you haven’t thought of.
These are only part of the “ninja tips” taught In our Case Interview E2E Secrets Program – besides the math and business intuition for long-term development, a key feature is the instant-result tips and techniques for case interviews.
Once you’ve mastered them, you can nail any case they throw at you!
For more “quality” practice, let’s have a mock case interview with former consultants from McKinsey, BCG, Bain, Oliver Wyman, Strategy& and many other consulting firms. They will help you identify your problem areas and give you actionable feedback, making your preparation much easier and faster.
Hi! This is Kim and welcome to another performance in the Tips & Techniques part of our amazing End-to-end program. You are about to hear a really interesting performance.
There is a common Myth that Profitability cases are easier. Well, for beginners, that’s may make sense, but I would argue that Profitability cases can be really tricky and candidates without good foundation will make about the same level of mistakes regardless of type of cases given.
The profitability case we are about to watch will show that. It’s a very unconventional
Profitability. It started out like a typical one but getting more and more tricky toward the end.
The candidate is fairly good in term of business intuition, but the Tips & Techniques aspect needs a lot of fine tune! Now let’s go ahead and get started!
It’s actually a little better to playback the case information and ask clarifications. The candidate does not distinguish between the two and do both at a same time. Also, the candidate was asking these clarifications in an unorganized and unstructured fashion. This is not something terrible, but could have been better, especially when this is the very first part of the case, where the crucial first impression is being formed.
My pitch would sound like this:
“That’s a very interesting problem and I am happy to get the chance to solve it. First of all let me tell you my understanding of the case context and key objectives. Then I would like to ask a few clarifying questions regarding a few terminology and concepts. Both of these are to make sure that I will be solving the right problem.
So here is my understanding of the case: The client is ABC. Here are some DEF facts about the situation we just talked about. And the key case question is XYZ.
Does that correctly and adequately summarize the case?”
Once the interviewer confirms, I would move to the clarification part as follows: “Now I would like to ask a few clarification questions. There are three of them: No 1, … No 2, … and No 3, …”
You may see above pitch as obvious but that’s a perfect example of how you should open any cases. Every details matters. We will point out those details in just a second. But before we do that, it’s actually very helpful if you can go back, listen carefully to the above pitch, and try to point out the great components yourselves. Only after that, go back to this point and learn it all together.
Alright, let’s break down the perfect opening.
First of all, you hear me say: “That’s a very interesting problem and I am happy to get a chance to solve it”. This seems trivial but very beneficial in multiple ways:
1. I bought myself a couple of seconds to calm down and get focused. 2. By nature, we as human unconsciously like those who give us compliments. Nothing better than opening the case with a modest compliment to the interviewer.
And (c) I showed my great attitude towards the case, which the interviewer would assume is the same for real future consulting business problems.
You should do that in your interviews too. Say it and accompany it with the best smile you can give. It shows that you are not afraid of any problems. In fact, you love them and you are always ready for them.
Secondly, I did what I refer to as the “map habit”, which is to always say what you are about to do and then do it. Just like somebody in the car showing the drivers the route before cruising on the road. The driver would love it. This is where I said: “Let me tell you my understanding of the case context and key objectives. Then ABC…”.
Third, right at the beginning of the case, I try to be crystal clear and easy to follow. I don’t let the interviewer confused between playing the case vs. asking clarification questions. I distinguish between the two really carefully. This habit probably doesn’t change the outcome of how the case goes that much, but it certainly significantly changes the impression the interviewer has of me.
Fourth, in playing back the case, each person would have a different way to re-phrase. But there are three buckets to always include:
1. Who is the client 2. The facts regarding the client and the situation and (c) The key question and the objective of the case.
Fifth, after playing the case context and objectives, I pause for a second and ALIGN with the interviewer: “Does it correctly and adequately summarize the case?”. This is a habit that every consulting manager loves for young consultants to do. Nobody wants first-year folks to spend weeks of passion and hard-work building an excel model that the team can’t use. This habit is extensively taught at McKinsey, Bain and BCG, so therefore interviewers would love somebody that exhibits this habit often in case interview.
Lastly, when asking clarification questions, you hear me number them very carefully to create the strong impression that I am very organized and structured. I said I have three clarifying questions. Then I number them as I go through each. No.1, No.2, and No.3.
Sometimes, during interviews it’s hard to know exactly how many items you are going to get. One way is to take timeout often to carefully plan your pitch. If this is not possible in certain situations, you may skip telling how many items you have; but you should definitely still number your question: No.1, No.2; and so on.
Just a moment ago, the candidate actually exhibited a good habit. After going through his clarification questions, the candidate ended by asking the “is there anything else” question. In this case, I actually give out an important piece of data.
Though this is not very common as not every interviewer is that generous in giving out data. But this is a habit management consultants have to have every day when talking to experts, clients, or key stakeholders. The key is to get the most data and insights out of every interview and this is the type of open-ended question every consultant asks several times a day.
To show of this habit in a case interview is very good!
There are three things I would like you to pay attention to:
First, it took the candidate up to 72 seconds to “gather his thoughts”. This is a little too long in a case interview. I intentionally leave the 72 seconds of silence in the recording so you get an idea of how long that is in real situations. But it’s worth-noting here is not only that. While in some very complicated and weird cases, it’s ok to take that long to really think and gather ideas. In this case, the approach as proposed by the candidate is very simple. For this very approach, I think no more than 15 to 20 seconds should be used.
No.2, with that said, I have told I really like the fact that this candidate exhibits the “map” habit. Before going straight to the approach he draws the overall approach first.
No.3. You also see here that the candidate tried to align the approach with me by asking my thoughts on it. As I just said on the previous comment, this is a great habit to have. Not only does it help reduce chance of going into the wrong direction in case interviews, but it also creates a good impression. Consulting interviewers love people doing it often!
Here we see a not-really-bad response that for sure could be much better. The candidate was going into the first branch of the analysis which is Revenue. I would fix this in 3 aspects:
First, even though we just talked about the overall approach, it’s still better to briefly set up the issue tree first then clearly note that you are going into one branch.
Second, this is not a must, but I always try to make my hypothesis as explicitly clear as possible. Here the candidate just implicitly made a hypothesis that the problem is on the revenue side. The best way to show our hypothesis-driven mindset is to explicitly say it.
Third, you hear this a ton of times in our End-to-End program but I am going to repeat it again and again. It is better to show the habit of aligning here too. Don’t just go into revenue, before doing that, give the interviewer a chance to agree or to actually guide you to Cost.
So, summarizing the above insights, my pitch would sound something like this:
“So as we just discussed, a profit problem is either caused by revenue or by cost. Unless you would like to go into cost first, let’s hypothesize that the problem is on revenue side. I would like to look deeper into Revenue. Do we have any data on the revenue?”
And while saying this, you should literally draw an issue tree and point to each as you speak.
There is an interesting case interview tip I want to point out here. Notice how the candidate responds after receiving two data points from me. He went straight into the next question without at least acknowledging the data received and also without briefly analyzing it.
I am glad that the candidate makes this mistakes… well, not glad for him but for the greater audience of this program. I would like to introduce to you the perfect habit of what you should react and do every time you have any piece of data during case interviews. So three things you need to do:
Step 1: Say … that’s an interesting piece of data. This helps the interviewer acknowledge that you have received and understand the data. This also buys you a little time. And furthermore, it’s always a good thing to give out modest compliments to the interviewer.
Step 2: Describe the data, how it looks, is there any special noteworthy trend? In this case, we should point out that revenue actually grew by more than 50%.
Also notice here that I immediately quantified the difference in specific quantitative measurement (in this case, percentage). Saying revenue went up is good, but it’s great to be able to say revenue went up by more than 50%.
Step 3: Link the trend identified back to the original case question and the hypothesis you have. Does it prove, disprove, or open up new investigation to really test the hypothesis? In this case, this data piece actually opened up new investigating areas to test the hypothesis that the bottleneck is within revenue.
My sample pitch for this step 3 would sound like this: “It’s interesting that revenue went up quite a bit. However, to be able to fully reject our hypothesis on the revenue, I would like to compare our revenue to that of the competitors as well.”
Then only at this point, after going through 3 steps above, I ask for the competitors’ revenue like the candidate did.
Notice here that I ended up asking the same question the candidate did. This shows that the candidate does have a good intuition and thought process. It’s just that he did all of these implicitly on his head.
In consulting case interview, it’s always good to do everything as explicitly as possible. Not only is it easier to follow but it helps show your great thought process.

Top Google system design interview questions
As a former software engineer and interviewer at Meta and Microsoft, I can say from my experience that system design interviews (SDIs) at top companies can be challenging for most candidates.
Most software engineers have never worked practically on such systems. Despite this lack of hands-on experience, candidates must be prepared to have in-depth theoretical discussions covering technologies they may have never interacted with.
Moreover, Google coding interviews are famously tricky. Google has extremely high standards for analyzing technical capabilities and a rigorous multi-phase interview loop designed to vet out suboptimal candidates.
Passing Google’s system design interview is the dream of many software engineers, but to do so, you need to be extremely well-prepared. Fortunately, Google is transparent about its expectations, which means you can succeed with proper practice and hard work.
Today, we’ll discuss the hiring process and the top system design interview questions commonly asked at Google.
The hiring process at Google
Google has an extremely rigorous hiring process that aims to filter the best technically capable candidates with a fair process, as illustrated below:

9 Case Study Examples, Plus a Useful Case Study Template
Writing a case study can help you pitch your services to prospective clients. Learn how to write one by studying successful examples and using a free template.
![case study interview questions google A magnifying glass on an orange background with three boxes displaying data points.](https://cdn.shopify.com/s/files/1/0070/7032/files/case_20study_20examples_1848x970.png?v=1718983793)
If you can write a résumé, you can write a case study. Just as a résumé shows potential employers how your experience can benefit their team, a case study highlights an existing client’s success story to demonstrate your business or product’s value to prospective clients.
A compelling case study includes relevant data without overwhelming your reader, considers the customer’s perspective, and demonstrates how you handled a specific challenge.
The best way to learn how to write one is by reading a stellar business case study example.
What is a case study?
A case study is a document business-to-business (B2B) companies use to illustrate how their product or service helped a client achieve their goals. A winning case study introduces the featured client, gives a brief description of their challenge or goal, and showcases the results they achieved with your help.
Businesses that provide software, tools, or consulting services often provide case studies to potential customers trying to choose between several options.
A company’s marketing team is typically responsible for writing case studies, but if you have a small business without a dedicated marketing team, don’t worry. Anyone can write a case study, and it’s a straightforward process if you use a template.
Why should you create a case study?
A case study brings your product or service to life for future customers with real-world examples. These success stories offer tangible results. Case studies are, thus, a form of social proof , but their power goes beyond a mere testimonial or review.
Since B2B services often are expensive and require approval from multiple decision-makers, typical forms of social proof often aren't enough to convince potential customers. Business customers want to be able to share compelling data with their teams, and that’s where the case study is beneficial.
How to write a case study
- Choose a template
- Interview your client or customer
- Describe the situation
- Identify the solution
- Present the results
1. Choose a template
You don’t necessarily need a template to write a case study, but it can make the process easier—especially if you haven’t written one before or need to write several at once.
You’ll notice that most business case studies take the same general format; after inputting the basics into the template, you can add your own personal flair. (That is, your branding and voice.)
2. Interview your client or customer
The client or customer interview is the heart of the case study. Identify several current or past clients willing to chat with you about their experiences. Look for repeat customers and those who reached out independently to tell you how much they enjoyed your product or service.
A phone interview is the best way to get conversational quotes, but you can correspond via email if your subject is short on time. Not sure what to ask? When social advertising agency Biddyco interviewed the VP of Marketing at Fellow , they asked him the following questions , according to their case study:
- What were the obstacles that would have prevented you from choosing/hiring Biddyco?
- What have you found as a result of hiring Biddyco?
- What specific feature or thing do you like most about Biddyco’s services?
- Would you recommend Biddyco and why?
The goal of the interview is to better understand your client’s experience with your product or service and grab a soundbite you can use as a testimonial in your case study. If you didn’t work directly with the client, you may also want to interview someone on your team who did to get more context.
3. Describe the situation
Give context to your case study with a brief description of the client’s business and the desired outcome that led them to seek your product or service. You can follow this general formula:
[Client’s name] is a [type of business] with [unique feature]. [Client’s name] came to [your business] seeking [client’s desired outcome] while [requirement].
Here’s an example of a one-sentence situation summary in the case study for Sharma Brands ’ client Feastables:
“Feastables, a better-for-you snacks company, came to us in need of a team to take the DTC setup off their plate.”
Advertising company Adgile, which created moving billboards for the non-alcoholic aperitif brand Ghia , has a longer description in its case study that provides background on the marketplace, but the heart of it is this:
“Ghia was seeking creative ways to break through the clutter of a crowded—and big-budgeted—adult beverage market, all while managing customer acquisition cost (CAC).”
4. Identify the solution
This section can vary depending on your field. Also described as “the action,” “the work,” or “the strategy,” the solution describes the strategic insights your company brought to your client’s problem or how your customer used your product to achieve their goals.
The basic formula: [Client’s name] partnered with [your business] to [service received].
Here’s an example from email marketing software Klaviyo’s case study featuring olive oil brand Graza:
“Graza uses Klaviyo’s granular segmentation tools to send automated flows and promotional campaigns to small, targeted groups of customers based on purchase frequency.”
This section describes exactly which of Klaviyo’s features Graza used (granular segmentation) and how they used it (to send automated flows to small, targeted groups), without getting into any outcomes or results yet.
5. Present the results
This section is where you’ll win over prospective customers and build trust. The basic formula is:
[Client’s name] used [service received] to [desired outcome].
Share how your product or service positively affected the client’s business, whether that’s cost savings, more clients, or improved company culture. According to a case study from community platform TYB, the results it delivered for skin care company Dieux were as follows:
“Dieux was able to create thousands of authentic, personalized referrals ahead of its new product launch plus live out its brand promise of transparency.”
Depending on your product or service, your results may include quantifiable outcomes (like thousands of referrals), intangibles (like living out your brand promise), or both, as in the case of TYB.
Real-world examples of case studies
Sharma brands for feastables, adgile media group for ghia, meta for lulus, tyb for dieux, biddyco for fellow, outline for heyday canning, klaviyo for graza, culture amp for bombas, kustomer for thirdlove.
A great way to write a case study is to look at a sample case study—or better yet, many. You’ll notice that wildly different businesses have case studies that follow roughly the same structure, which is why we recommend using one of our free case study templates to write yours. Learn from this mix of business, design, and marketing case study examples:
Sharma Brands is a branding agency founded by Nik Sharma , “The DTC Guy.” Sharma Brands keeps its case study featuring snack company Feastables short and sweet, breaking it down into three chronological sections: the situation, the work, and the outcome.
The Sharma Brands case study is a good example of how to incorporate meaningful results without sharing actual numbers (which the client may not wish to make public) or getting into an in-depth analysis.
Instead of metrics, Sharma Brands lists the tasks it executed:
- “Successfully launched their DTC site.”
- “Simultaneously launched on GoPuff with no downtime.”
It also lists some general achievements:
- “Broke Shopify records in the first 24 hours of launch.”
- “All revenue and engagement metrics were highly exceeded.”
![case study interview questions google Adgile case study for Ghia showing ads on trucks.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed_cc88d0d3-8086-4cd1-83f7-bc0d404cdd05_1848x970.png?v=1718985087)
Adgile Media Group creates outdoor advertising by providing brands with mobile billboards. Unlike traditional outdoor advertising, Adgile also tracks the digital impact of its IRL campaigns.
Adgile’s case study featuring the non-alcoholic beverage brand Ghia is the perfect place to show off the metrics it collects, like:
- 78% homepage visit lift
- 91% conversion lift
- 82% lift on its Find Us page
- Increase in brand awareness and recall, more than 75% over the competition
Meta, the social media and digital advertising platform, does something in its case studies that every company can replicate. Instead of saving the numbers for the results section, Meta provides a brief overview near the top. This breaks up the text visually, provides a quick snapshot for anyone who doesn’t want to read the full case study, and intrigues those curious to know how they achieved those numbers.
![case study interview questions google A screengrab of Lulu's case study results.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed-1_1efdcfaf-bbf9-4aaa-b347-b734fb74198c_1848x970.png?v=1718985084)
Meta’s case study for the clothing company Lulus starts by teasing its most impressive stat:
“The women’s fashion ecommerce company compared the performance of a Meta Advantage+ shopping campaign with Advantage+ catalog ads versus its usual ad campaign setup and saw a 47% increase in return on ad spend using the Advantage+ products.”
It then presents three key figures in a visually appealing design, drawing clear attention to the impact it had on this customer.
TYB is a community platform that rewards fans for creating user-generated content . TYB’s case study for Dieux details how the skincare brand used its platform to involve customers in product testing.
It also does something small worth noting: Instead of sticking the call to action at the bottom of the case study, TYB places a “request demo” button at the top of the page. That way, anyone compelled by the results of the case study can take the next step immediately.
![case study interview questions google Screengrab of Dieux's referral with request a demo button and image of a statue of cupid.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed-4_4bebf392-762f-44c0-8994-cd0c8556f9bb_1848x970.png?v=1718985087)
Advertising agency Biddyco took a unique approach to its case study for the coffee- and tea-gear company Fellow . Unlike other business case study examples that use the typical situation-solution-results format, Biddyco structured its case study as an extended testimonial, with a series of questions like, “What specific feature or thing do you like most about Biddyco’s services?”
In addition to client feedback, Biddyco also highlights a few key accomplishments under the heading “All You Really Need to Know.”
![case study interview questions google Screengrab of Biddyco's case study results.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed-3_44b5fc4d-b01e-490c-962f-ffc443149d42_1848x970.png?v=1718985087)
A branding studio like Outline won’t approach case studies in the same way an advertising platform like Meta would. What matters here isn’t cost per impression or ROAS, it’s how everything looks.
That’s why Outline’s case study for Heyday Canning is relatively light on words and heavy on imagery. If your work is more visual than numerical, your case study is a great place to show your behind-the-scenes process.
For example, Outline shows the label design alongside images of the cans on the shelf and provides a brief description of the design inspiration. This example shows how you can have a design-focused case study that still tells a compelling story.
![case study interview questions google Heyday Canning product display with highligh on Apricot Glazed.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed-6_ee2f4b96-c227-4bd2-b13b-161eb09537e2_1848x970.png?v=1718985092)
Klaviyo , an email marketing software company, puts numbers front and center in its case study for the olive oil company Graza . If your product or service involves tracking metrics like email open rates, revenue, and click rates, highlight those stats in a larger font size, as Klaviyo did.
Klaviyo’s case study for Graza also shows you don’t necessarily need to fix a problem to create a great case study; you can also simply help your client achieve their goals. According to Klaviyo’s case study, Graza’s challenge was to create strong customer relationships.
![case study interview questions google Screengrab of Graza case study results and image of Graza products display.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed-2_9edfed95-38c8-4e74-9c24-b8133f125f80_1848x970.png?v=1718985103)
How do you write a compelling case study if your service doesn’t involve tangible metrics or flashy design? For the performance management software company Culture Amp , it’s highlighting key statistics about the subject of its case study , sock company Bombas .
Like Meta and Klaviyo, Culture Amp highlights three numbers in large font. But these numbers are stats about their client Bombas, not Culture Amp’s services: “120+ employees,” “25M+ items donated,” and “$100M+ in revenue for 2018.”
Instead of showing off the results it achieved for Bombas, these numbers let prospective clients know that Culture Amp works with big, important companies on their performance management process.
Choosing a customer relationships management ( CRM ) platform is a big decision. Switching platforms—as bra company ThirdLove did in this case study from customer support platform Kustomer—can involve lengthy data migration, customization, and employee onboarding.
That’s why it makes sense that Kustomer’s case study for ThirdLove is a four-page-long PDF and not a blog post. If your case study involves a long, detailed analysis, follow Kustomer’s example and make two versions of your case study.
The first page is an executive summary, with about a paragraph each describing the challenge and results. If after reading the first page, you want to learn more, you can dive into the rest of the case study, but you don’t have to read the entire thing to get a sense of how Kustomer collaborated with ThirdLove.
![case study interview questions google Screengrab of ThirdLove case study with image of bra display.](https://cdn.shopify.com/s/files/1/0070/7032/files/unnamed-5_92a7ddd4-4e17-44b5-b020-84a0b6a2ebec_1848x970.png?v=1718985099)

Google Interview Experience For SDE 2024
I have several years of experience as a Software Development Engineer (SDE). Initially, I worked at a media conglomerate, working as a full-stack developer. Later, I transitioned to a SAAS company, where I honed my skills further. Currently, I am employed at a leading fintech company.
A Google recruiter reached out to me regarding a role. While my expertise didn’t include Java or angular, the recruiter assured me that the tech stack was not a barrier—as long as I performed well in the interview rounds.
Total Number of Interview Rounds in Google -6
Mostly just long telephone conversations with the recruiter trying to know more about me, my experiences, my tech stack etc.
It was a video interview with a developer from Singapore. it was the most chill round of them all, I was given a JS compiler with no auto-correct or code completion capabilities. The problem was simple ” Find all matches of a small string str2 in a big string str1″ I showed the most naïve solution and then sequentially made it better, he wanted me to explain how it works so I had to do a little whiteboarding where I explained the whole flow of the algorithm right down to creating hashes. Then I had to explain the big o notation, and why it’s linear. etc. By the time we finished the discussion almost 45 minutes were over I thought I’d get another question but that didn’t happen.
Again a video interview with someone from the US. As I was only free after my regular work I didn’t receive any Indian interviewers. Most of my interviews were at 9 pm or 10 pm IST. He explained to me a problem statement, which resulted in a rope or cord data structure. ( ref wiki). once I implemented the structure the questions were;
- Find out the length of both ends from a given node
- Find substrings (i,j) from the structure etc.
This round was with someone from Zurich, and it was the same question but explained differently. I think they don’t communicate previous rounds’ details with the panelists, so I was lucky to be getting the same question again, I was prepared this time but the queries were a little different.
- Find out if two cords are the same or different
- Find if a cord contains another etc.
This was the most hectic round as we kept coming back and forth with problems and solutions. The question statement boils down to this “Given a stream of share market data with potential updates to older values, how can we efficiently find the maximum, minimum, and current values?” I came up with lots of different solutions to this, some were more space-optimized, while some were more time-optimized. but I could sense he wasn’t totally satisfied, so we ended the interview on a bittersweet note and I realized it was a bad one.
The last round is called the googlyness round. it was the round I enjoyed most as there was not much to prepare we sat down a had a chat about my experiences. The questions were like this
- Share your most cherished accomplishments in your career.
- Describe the most challenging moments you’ve faced in your career.
- Highlight instances where you demonstrated strong leadership.
- Recall moments when you exhibited courage by challenging the status quo.
- Discuss how you’ve fostered inclusion within your team. and similar things.
Preparing the folder: after the interviews were done the recruiter told me the feedback and the ratings after each round. So I had a mental image of the folder. Since one of my rounds went bad, it wasn’t looking good. Still, I managed to get a referral from one of my friends in Google as I was told that helps. After a few weeks, the recruiter reached out saying no managers were willing to accept my folder and that I should try again after 6 months but I moved abroad after a few months and lost interest. Even though I wasn’t selected it was an overall positive experience for me and the recruiter was helpful every step of the way.
