Case Study Benefits

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.

Case interview questions

Case interviews at management consulting firms are among the most difficult job interviews, but they are also quite predictable. Once you know the types of questions they ask, preparation is straightforward. Using years of experience at McKinsey, as well as field reports from thousands of candidates, I’ve crafted a list of 8 common case interview questions, and in this article, I’ll show you how to answer each of them.

Case interview questions – Overview

Types of case interview questions .

Most questions in case interviews belong to one of these 9 types: 1. Framework/issue tree questions 2. Market-sizing and guesstimate questions 3. Valuation questions 4. Brain teaser questions 5. Chart insight questions 6. Value proposition questions 7. Information questions 8. Math problems 9. Solution-finding questions In this article, we’ll discuss how to answer each question, along with the necessary tips and tricks.

How to answer case interview questions

There are the fo ur basic steps to answer case interview questions:

This general outline may vary depending on each type and each question – for example, brain teasers or information questions need only the last step, while market-sizing and framework questions need all four steps to deliver the perfect answer.

Type 1 – Framework/Issue tree questions

interview case study questions and answers

If the interviewer asks you to identify factors contributing to a problem or to break down an entity (such as the revenue of a business), he/she is telling you to draw an issue tree. And to draw a spot-on issue tree, you need to master consulting problem-solving foundations , the MECE principle , and common consulting frameworks . You should check out our other articles on these topics before moving on, because mastering the issue tree is the key to acing every possible case interview. You also need good business intuition to draw good issue trees, so that’s all the more reason to start reading every day.

interview case study questions and answers

Job: Factors from the job itself. Further divided into 3 sub-branches

Company: Factors from the work environment within the restaurant chain, surrounding the affected jobs. Further divided into 2 sub-branches

Competitors: Factors from outside the restaurant chain, related to competing job offers. Further divided into 2 sub-branches.

For detailed guides on issue trees, frameworks and their principles, see the articles on Issue Trees , Case Interview Frameworks, and MECE Principle

Type 2 – Market-sizing & guesstimate

These questions go along the lines of “How many trees are there in Central Park?” or “What’s the market size of pick-up trucks in the USA?” The key to nailing market-sizing and guesstimate questions lies in not the closest results, but the most logical and structured approaches. In fact, the interviewer expects you to follow these four steps:

Unless you come up with something about 10 times the reasonable estimate, don’t worry about being “wrong” – the interviewer is unlikely to have a “correct” number in mind, he/she just wants to see your structured mindset. This question type is so common, we devote a whole article to it, and our Case Interview End-to-End Secrets Program have a separate package on these questions. Check out our comprehensive guide on Market-Sizing & Guesstimate Questions for more details! Now, here’s a quick example for you to try and get used to this type:

Market-Sizing & Guesstimate Questions

How to Estimate Logically and Structurally

Break down the problem: The global smartphone market can be divided into three segments – developed countries, developing countries, and undeveloped countries. In each segment, the annual unit sales of smartphones depend on four variables:

Solve each piece:

=> Estimated global smartphone market: 1.53 billion units per year => Actual 2019 global smartphone sales: 1.37 billion units (error margin: 11.7%) This market-sizing question is solved using a four-step process, which is explained in this article: Market-Sizing & Guesstimate Questions

Type 3 – Valuation questions

Valuation questions are a blend of guesstimation/market-sizing, math, and business. They also require basic finance knowledge. There are three ways to estimate the value of a business:

In real case interviews, you have to justify your approach then ask the interviewer to give you the necessary data.

Type 4 – Brain teasers

Brain teasers are riddles designed to test unconventional, creative, and logical thinking. A famous example of this is Accenture’s “How do you put a giraffe in a fridge?”. Although not as popular as before, brain teasers might still appear in consulting interviews; therefore, you should spend some time to prepare. Most brain teasers can be allocated into these seven types:

require you to bypass misleading details to spot what’s important.
require you to identify trends and patterns, then fill in the blanks.
require you to use stories to explain weird and seemingly impossible situations.
require you to find alternative meanings to words to explain impossible situations.
require you to identify meanings hidden behind the organization, composition, and visual demonstration of letters.
require you to estimate vague, sometimes unverifiable figures; we’ve just covered these in the previous section.

In our Case Interview End-to-End Secrets Program , there are +200 brain teasers to help you prepare for these “unpredictable” questions. You can also read our article about Case Interview Brain Teasers for insights on all of these exciting brain teasers, as well as 30 example questions and answers!

Brain Teaser Questions

Cracking the Most Unpredictable Interview Questions with 30 Examples

Answer Key Open the fridge, put the giraffe in, then close the fridge. The question never says how big the fridge or the giraffe is. For the logic and approach behind each kind of brain teasers, see the article on Brain Teasers.

Type 5 – Chart insight questions

You can’t be a management consultant without mastering the use of charts – the complex, scary-looking real-world charts such as those included in our Case Interview End-to-End Secrets Program. In management consulting and case interviews, most charts are one (or a combination) of these four basic types:

To read these charts and answer chart-insights questions effectively, you must follow a structured, comprehensive process:

You can find a more detailed guide in the Charts section in our article about Consulting Math.

interview case study questions and answers

Type 6 – Value proposition questions

No business or consulting candidate can succeed without understanding the customers! Value-proposition questions are not only about correctly identifying customer preferences, but also about analyzing and delivering the answer in a structured fashion. The former relies heavily on business knowledge and intuition, but the latter can be trained methodically and quickly. Personally, I use a “double issue-tree” – essentially a table with customer segments on one axis and proposed values on the other: For segmenting customers, you can use the following table. However, don’t over-rely on it, since there may be more relevant and insightful question-specific segmentations.

In some cases, clarification is also necessary – both to avoid “answering the wrong question” and to narrow down the range of customers/values you need to cover in the answer.

Cost factors

Physical factors

Emotional factors

Type 7 – Information questions

“Information questions” essentially ask if the piece of data you use is obtainable in the first place. In real consulting work, data is not always available – client team members may refuse to cooperate or there’s simply no data on the subject. There are many kinds of information sources in case interviews/consulting works, but I’ll divide them into primary and secondary sources. Primary sources means you must do the research yourself (or pay someone else to do it for you), such as customer surveys or mystery shoppings. If someone already did that research, and you use their results, it’s called a secondary source – you can get these from the client , the consulting firm you work for, or third-parties such as market research firms or external industry experts. You can find out more about these sources and how to cite them in real case interviews through this free Prospective Candidate Starter Pack, which contains a glossary of data sources in consulting. Our Prospective Candidate Starter Pack has a sheet containing all the possible sources of information in case interviews and consulting projects, among numerous other free resources; you can download and use it to answer these questions, by subscribing to our newsletter at the end of this article.

Type 8 – Math problems

When you have to do the math, perform back-of-the-envelope calculations in a structured fashion, and say out loud what you’re writing. For one thing, it’s safe; for another, you show that you’re careful, organized, and reliable – just like actual consultants. We have a Math Practice Tool right here! Use it every day, and you’ll be a master of mental calculations in no time flat! We have a dedicated article on Consulting Math, which you should definitely read.

Type 9 – Solution-finding questions

When dealing with solution questions, keep these four points in mind:

interview case study questions and answers

Last but not least, deliver at least two solutions, preferably three to five. Otherwise, you’ll appear uncreative and lazy to the interviewer’s eyes. Nailing these questions relies on having excellent business intuition; our Case Interview End-to-End Program has a dedicated Business Intuition package, but you should also train a habit of reading consulting and business articles daily, to sharpen your business mind.

Reminders on case interview questions

The questions are not clear-cut in candidate-led cases.

There are two extremes in consulting case interview format: interviewer-led (McKinsey) and candidate-led (BCG, Bain).

This list, therefore, is much more relevant to the interviewer-led format; nonetheless, this guide is still quite beneficial for candidate-led cases, because when solving that big problem, you’ll have to tackle small issues similar to the 8 aforementioned question types.

Mastering the fundamentals is crucial to consistent performance

Although it’s good to study the case interview questions, it is no substitute for mastering the fundamental principles. Learning the exercises without the basics is like building a house without a foundation. My poor neighbor’s house developed a huge crack right down the center because of its weak foundation, so make sure to build your case interview prep a strong one by knowing the basics first. Once you’ve mastered the fundamentals, you’ll become much more flexible – this quality is getting increasingly important because case interviews are getting less predictable, and more realistic. If you haven’t, I advise you to read these articles (especially the first 4) before practicing the question types:

Expect the unexpected

If you study those nine question types, rest assured that you’ve covered the majority of questions in case interviews. However, these are not all the possible questions you might be given. In actual cases, there are always questions that cannot be categorized neatly. If you do not prepare for these questions, it’s easy to be thrown off-balance. So, how do you prepare for “the unexpected”?

Hacking The Case Interview

If you are interviewing for a business strategy or operations role at Google, there is a high chance that you will be given at least one case interview or case study interview. Roles at Google that have case interviews as part of the interview process include:

In order to land these jobs at Google, you will need to pass every single one of your case interviews. While Google case interviews may seem ambiguous and intimidating at first, know that they can be conquered with the right preparation and practice.

If you are unfamiliar with how to solve or prepare for Google case interviews, we have you covered. In this comprehensive Google case interview guide, we’ll cover:

What is a Google Case Interview?

Google case interviews, also known as Google case study interviews, are 30- to 45-minute exercises in which you are placed in a hypothetical business situation and are asked to find a solution or make a recommendation.

To do this, you’ll create an overall framework that shows what approach you would take to solve the case. Then, you’ll collaborate with the interviewer, answering a mix of quantitative and qualitative questions that will give you the information and data needed to develop an answer. At the end of the case, you’ll deliver your recommendation.

Case interviews have traditionally been used by consulting firms to assess a candidate’s potential to become a successful consultant, but many companies with ex-consultants now use them to assess an interview candidate’s capabilities. Since Google hires so many former consultants in its business roles, you’ll likely encounter at least one case interview in your interview process.

The business problems that you’ll be given in a Google case interview will likely be real challenges that Google faces today:  

Depending on what team at Google you are interviewing for, you’ll likely be given a business problem that is relevant to that specific team.

Although there is a wide range of business problems you could possibly be given in your Google case interview, the fundamental case interview strategies to solve each problem is the same. If you learn the right strategies and get enough practice, you’ll be able to solve any Google case interview.

Why does Google Use Case Interviews?

Google uses case interviews because your performance in a case interview is a measure of how well you would do on the job. Google case interviews assess a variety of different capabilities and qualities needed to successfully complete job duties and responsibilities.

Google’s case interviews assess five major qualities:

Since all of these qualities can be assessed in just a 30- to 45-minute case, Google case interviews are an effective way to assess a candidate’s capabilities.

The 6 Steps to Solve Any Google Case Interview

In general, there are six steps to solve any Google case interview or case study interview.

1. Understand the case

Your Google case interview will begin with the interviewer giving you the case background information. While the interviewer is speaking, make sure that you are taking meticulous notes on the most important pieces of information. Focus on understanding the context of the situation and the objective of the case.

Don’t be afraid to ask clarifying questions if you do not understand something. You may want to summarize the case background information back to the interviewer to confirm your understanding of the case.

The most important part of this step is to verify the objective of the case. Not answering the right business question is the quickest way to fail a case interview.

2. Structure the problem

The next step is to develop a framework to help you solve the case. A framework is a tool that helps you structure and break down complex problems into smaller, more manageable components. Another way to think about frameworks is brainstorming different ideas and organizing them into different categories.

Before you start developing your framework, it is completely acceptable to ask the interviewer for a few minutes so that you can collect your thoughts and think about the problem.

Once you have identified the major issues or areas that you need to explore, walk the interviewer through your framework. They may ask a few questions or provide some feedback.

3. Kick off the case

Once you have finished presenting your framework, you’ll start diving into different areas of your framework to begin solving the case. How this process will start depends on whether the case interview is candidate-led or interviewer-led.

If the case interview is a candidate-led case, you’ll be expected to propose what area of your framework to start investigating. So, propose an area and provide a reason for why you want to start with that area. There is generally no right or wrong area of your framework to pick first.

If the case interview is interviewer-led, the interviewer will tell you what area of the framework to start in or directly give you a question to answer.

4. Solve quantitative problems

Google case interviews typically have some quantitative aspect to them. For example, you may be asked to calculate a certain profitability or financial metric. You could also be asked to estimate the size of a particular market or to estimate a particular figure.

The key to solving quantitative problems is to lay out a structure or approach upfront with the interviewer before doing any math calculations. If you lay out and present your structure to solve the quantitative problem and the interviewer approves of it, the rest of the problem is just simple execution of math.

5. Answer qualitative questions

Google case interviews will also typically have qualitative aspects to them. You may be asked to brainstorm a list of potential ideas. You could also be asked to provide your opinion on a business issue or situation.

The key to answering qualitative questions is to structure your answer. When brainstorming a list of ideas, develop a structure to help you neatly categorize all of your ideas. When giving your opinion on a business issue or situation, provide a summary of your stance or position and then enumerate the reasons that support it.

6. Deliver a recommendation

In the last step of the Google case interview, you’ll present your recommendation and provide the major reasons that support it. You do not need to recap everything that you have done in the case, so focus on only summarizing the facts that are most important.

It is also good practice to include potential next steps that you would take if you had more time or data. These can be areas of your framework that you did not have time to explore or lingering questions that you do not have great answers for.

Google Case Interview Examples and Answers

Example #1:  What differences would you take into account when selling a product to a client in India versus a client in Argentina?

Sample solution: To answer this, create a framework that shows the most important characteristics or qualities of each country that you would want to look into. For example, one potential framework may look into the customer needs and preferences, the competitive landscape, market trends, and Google’s capabilities across the two countries.

Example #2:  If you were a Google Search competitor entering a new market and had a small market share, how would you convince advertisers to advertise with you?

Sample solution: To answer this question, you should be familiar with Google Search. You can create a framework that outlines the product’s strengths and weaknesses so that you can identify gaps in customer needs. 

At a high level, the strengths of Google Search is that it has the widest reach since it is the most used search engine. It also has high targeting specificity since it has lots of data on long-tail keywords. However, the main drawback is how competitive and expensive it can be for advertisers to use. Customer service can also be slow for smaller customers given the number of customers Google services. Finally, the product can be complicated for advertisers to set up initially.  Therefore, when entering a new market as a Google Search competitor, it may make sense to target customers with smaller budgets and sell them on low-prices, fast customer service, and ease of set up.

Example #3:  What are three areas that Google should invest in?

Sample solution: To answer this question, it may be helpful to clarify what Google’s primary objective is. Are they looking to increase profits, revenues, or number of users? The ideas that you brainstorm may vary depending on their actual goals.  Next, develop a framework to organize your ideas. You may want to think about areas of investments as short-term investments, medium-term investments, and long-term investments.

Example #4:  If you were the CEO of AdSense, what would be your strategy to improve the product?

Sample solution: As always, create a framework to help you organize your ideas in a clear and easy to follow way. To improve AdSense, you can think about improving the product for advertisers, improving the product for search users, and improving the product for Google’s profitability. Using a framework like this one will help you consider all of the different ways that AdSense can be improved.

Example #5:  How much money do you think YouTube makes daily from ads?

Sample solution: This is an estimation question. Before doing any math calculations, make sure to lay out a structure or approach for how you would estimate this figure. 

You may want to start by estimating the number of people in the world, the percentage that use YouTube, the percentage that use YouTube on any given day, the average amount of time spent on YouTube in a day, the number of ads seen for that period of time, and then estimating the amount YouTube earns per ad that is shown. Multiplying all of these figures will give you your answer.

Example #6:  How would you set the price for the YouTube masthead? The YouTube masthead is a digital billboard placed on YouTube’s homepage for 24 hours, reaching about 60 million people.

Sample solution: In general, there are three ways to price a product: pricing by the cost to produce the product, pricing by the economic value the product provides customers, and pricing by the price of competitors’ similar products.

Since the cost of putting up a digital billboard is minimal, the first pricing strategy is not helpful. Looking at the second pricing strategy, you can price the digital billboard based on how much it would have cost the potential customer to get 60 million ad impressions. Looking at the third pricing strategy, you can look into how much other types of advertising that reach a similar number of people costs. For example, you could look into how much Super Bowl ads cost.

Example #7:  How would you market the Google Ads product to a potential client?

Sample solution: To develop an effective marketing strategy, you may want to look into the client’s needs, competitor offerings, and Google Ads’ features or benefits. Exploring these three areas will help you identify the features or benefits of Google Ads that are superior to competitor products that the client values.

Example #8:  How would you estimate the market size of Google display ads on websites?

Sample solution: This is another estimation question. As always, outline a structure before you begin doing any math calculations. 

You may want to start by estimating the global population, estimating the percentage that have internet, estimate the average number of sites visited per day, estimate the percentage of websites that have ads, estimate the percentage of these websites that use Google display ads, estimate the revenue Google generates per ad. If you multiply the product of these figures by 365 days in a year, you’ll get an estimate of the market size of Google display ads.

Example #9:  How would you determine the number of staff members needed in the customer support team next year?

Sample solution: One potential approach for solving this question could look like the following. 

Start with Google’s annual revenues and estimate the average revenue generated per customer to determine the number of customers Google services. For each customer, estimate the frequency in which they call customer support and the average length of a support call. Assuming that a staff member works eight hours per day, you can estimate the number of staff members you’d need to meet the volume of support calls.

You may need to grow this number by Google’s historical growth rate to account for expected revenue growth next year.

Example #10:  If you were setting up a new ecommerce business, what are the things you would look at?

Sample solution: This is a market entry case. Potential areas you should consider looking into in your framework include: the attractiveness of the market, the competitive landscape, the company’s capabilities, and the expected profitability.

Example #11 : How should YouTube deal with spam?

Sample solution: There are many different ways to deal with spam. To ensure that you brainstorm ideas in a clear and comprehensive way, develop a framework to categorize all of the different ways of dealing with spam. You may want to think about this as: preventing spam from being posted, detecting spam, and removing spam.

Example #12 : Let’s say that Google is considering acquiring iRobot, a company that builds consumer robots, such as the Roomba. What would you consider when deciding whether to make this acquisition?

Sample solution: This is an acquisition case. To determine whether or not this is an attractive acquisition, you may want to look into: the attractiveness of the consumer robots market, the attractiveness of iRobot as a company, the potential synergies from the acquisition, and the financial implications of the acquisition.

Example #13 : Estimate the time it takes a Google Street View car to collect footage in a city.

Sample solution: To answer this question, first clarify which city the interviewer is talking about. Then, outline your approach for how you would do this calculation. 

You might want to start by estimating the length and width of the city area. Then, estimate how wide a street is and the average distance between streets. If you think of a city as a grid that consists of vertical and horizontal lines, you can use these estimates to calculate the total street length in the city.

Afterwards, estimate the average speed of a Google Street View car, taking into traffic and stoplights. Dividing the total street length by the average speed of a Google Street View car will get you an estimate of how long it would take to collect footage.

Example #14 : How would you define the strategy for YouTube over the next 5 years?

Sample solution: This question is very similar to Example #3. Before answering, it may be helpful to clarify what YouTube’s primary objective is. Are they looking to increase profits, increase number of users, or increase user engagement? You may want to think about strategy as short-term strategy and long-term strategy.

Example #15 : Let’s say that Google is considering getting into the ride share business. What should they consider when making the decision on whether or not to enter?

Sample solution: This is a market entry case and the approach is similar to Example #10. Potential areas you should consider looking into in your framework include: the attractiveness of the ride share market, the competitive landscape, the company’s capabilities, and the expected profitability.

Google Case Interview Tips

Below are eight of our best tips to help you perform your best during your Google case interviews.

1. Familiarize yourself with Google’s business model

If you don’t understand Google’s business model, it will be challenging for you to do well in their case interviews. Therefore, you should know that Google makes the majority of its revenue by selling advertising and you should be familiar with the products and services that Google offers for the specific team you are interviewing for.

2. Read recent news articles on Google

Often, the cases you’ll see in a Google case interview are real business issues that the company faces. Reading up on the latest news on Google will give you a sense of what Google’s biggest challenges are and what major business decisions they face today. There may be a good chance that you’ll be given a case that is similar to something that you have read in the news.

3. Verify the objective of the case 

Answering the wrong business problem will waste a lot of time during your Google case interview. Therefore, the most critical step of the case interview is to verify the objective of the case with the interviewer. Make sure that you understand what the primary business issue is and what overall question you are expected to answer at the end of the case.

4. Ask clarifying questions

Do not be afraid to ask questions. You will not be penalized for asking questions that are important and relevant to the case. 

Great questions to ask include asking for the definition of an unfamiliar term, asking questions that clarify the objective of the issue, and asking questions to strengthen your understanding of the business situation.

5. Do not use memorized frameworks

Interviewers can tell when you are using memorized frameworks from popular case interview prep books. Google values creativity and intellect. Therefore, make every effort to create a custom, tailored framework for each case that you get.

Read our comprehensive case interview framework guide to learn how to create outstanding frameworks.

6. Always connect your answers to the case objective

Throughout the case, make sure you are connecting each of your answers back to the overall business problem or question. What implications does your answer have on the overall business problem?

Many candidates make the mistake of answering case questions correctly, but they don’t take the initiative to tie their answer back to the case objective.

7. Communicate clearly and concisely

In a Google case interview, it can be tempting to answer the interviewer’s question and then continue talking about related topics or ideas. However, you have a limited amount of time to solve a Google case, so it is best to keep your answers concise and to the point.

Answer the interviewer’s question, summarize how it impacts the case objective, and then move onto the next important issue or question.

8. Be enthusiastic

Google wants to hire candidates that love their job and will work hard. Displaying enthusiasm shows that you are passionate about working at Google. Having a high level of enthusiasm and energy also makes the interview more enjoyable for the interviewer. They’ll be more likely to have a positive impression of you.

Welcome back for more help preparing to ace your consulting interviews!

We mentioned on the Case Interview Prep page that practice is the key to passing your consulting interviews. To practice, you’ll need some examples of case interview questions an answers to work with.

We’ve got links to loads of them below.

In addition, we have:

Get ready to dive deep into structuring your analysis of business problems, identifying the key issues, and recommending solutions!

How to Use Case Interview Examples to Ace Your Case

1. start your case interview preparation early..

You’ll need to practice dozens of case interview examples to get good enough to receive an offer from one of the top consulting firms. This is not something you can cram the night before an interview.

Start as soon as possible.

2. Don’t Read Straight through Sample Case Interview Examples or Passively Watch Videos.

Some people think that the best way to improve their chances of passing a case interview is by reading as many cases interview examples as they can.

This is like reading about how to play tennis but never picking up a racket. To get better at tennis, for example, you need to actually pick up a ball and be active. The same applies to your interview preparation.

Stop and think at each step in the case interview question. Come up with your own answer and say it out loud. Practice driving each part of the case interview example yourself.

After you’ve developed your answer, compare it to the suggested answer for the case.

What did you get right?

How did your answer and the case interview example answer differ?

Are there things you miss consistently across multiple case interview examples?

The answers to these  case interview examples can look simple when you just read through them, but it’s not easy to come up with all the key aspects of the solution on your own.

3. Find Partners to Practice Case Interviews with.

Teamwork is an important part of consulting work, so get ready for it now. Find a case interview practice partner, preferably someone else who’s applying to jobs in the management consulting industry because they’ll know more about what recruiters are looking for.

Practicing cases with a partner provides the opportunity to get feedback from someone else on what you’re doing well and what you need to improve. Additionally, you’ll learn a lot by watching how your partner solves sample case studies.

Look for aspects of their approach that are effective as well as what they could do better. Working with a partner will make your consulting interview practice feel more real.

Similar to how you need a tennis partner to feel what is like to play tennis, you need a case partner to experience what a case interview is like.

4. Master the 4 Parts of the Case Interview.

In our article on Case Interview Prep , we discussed the 4 parts of the case interview: the opening, structure, analysis, and conclusion. As you practice with consulting case interview examples, practice each of these 4 parts to ensure you’re strong at them all.

5. Avoid Case Burnout.

A case zombie is someone who’s grown tired of casing from doing too much of it. Their answers feel rehearsed, not conversational. 

They may seem bored, not engaged in solving the problem. They’ll be less creative in their solutions. They certainly won’t pass the airport test!

Avoid becoming a case zombie by practicing smarter, not harder.

Video: Case Interview Examples – Questions & Answers

In the following case interview example, Davis Nguyen, founder of My Consulting Offer, talks with  Dan , an MCO coach and former BCG consultant and interviewer. Their discussion of BCG’s GenCo case is broken into 4 parts of the case interview.

In their case interview example, Davis and Dan demonstrate how to approach the business problem. They also provide examples of good answers vs. exceptional answers. Take note of what differentiates a good case interview answer from an exceptional answer so that you can not only get through your interview, but ace it.

Remember, don’t just watch the video. Stop the video and provide your own answer before listening to Dan’s  answer to the case question.

Step 1: Case Interview Example Opening – Ensure you understand the client and the problem you’ll be solving in the case.

Step 2: case interview example structure – break the problem down into smaller parts. make sure you cover all key case issues., step 3: case interview example analysis – ask questions, gathering information from graphs and charts provided by the interviewer, do case math, and provide insight into the client’s business problem based on what you learn., step 4: case interview example recommendation – develop a rational recommendation for the client based on all you’ve learned throughout the case interview., tips for acing your consulting case interviews – the difference between average & exceptional, case interview opening.

The opening is a great point to ask “dumb” questions because, at this point, you’re not expected to know much about the client and their business. 

Here your goal is to understand the client, their business, and what a successful project will look like.

Don’t shy away from asking for clarification on things that will help you better understand the business problem and solve it. For example, if you don’t know how life insurance works and the case is about life insurance, then ask.

After ensuring you understand the client and their problem, the next thing to ask about is key metrics of success. 

For example, the client may want to find new avenues for growth. Are they looking for a 5% increase in revenue or to double their business?

Finding out what success looks like in the client’s eyes will ensure you work to deliver a solution that meets their expectations, not one that’s underwhelming.

After you find out what success looks like, ask further probing questions to better understand the client, their business, and any constraints on solving the case.

Examples of Relevant Questions to ask Your Interviewer 

Examples of relevant questions about the client might include the geography they operate in or the sector of their industry they are strongest in. 

Examples of relevant questions about their business might include what products or services are most profitable or most important to their customers. 

Examples of relevant questions about the problem might include whether there are any costs that can’t be cut or what the maximum amount the client is able to invest in developing a new product. 

Asking these types of questions up front will give you a better context for solving the client’s problem and make it more likely that you will solve the case interview.

Case Interview Structure

You’ll need a framework to make sure your analysis covers all key aspects of the consulting case. 

You can use one of the many standard Case Interview Frameworks we’ve outlined , but top interviewees develop their own framework for analyzing the case interview question. 

Their frameworks may include pieces of one or more of the standard frameworks but are tailored to the particular business problem they’re discussing. 

Good frameworks are hypothesis-driven, that is to say they can be tested similar to the science experiment, so that the answer is either a “yes” or “no.” For example, examining your bank account to see, “if I have $400 for a ticket” is an example.

Second, good frameworks cover all topics relevant to the answer. For example, if the client is opening up a new hotel in a foreign country, checking out the existing competition should be part of the framework.

As you study more about interactive case interviews and practice them you’ll develop a sense for what factors are relevant or not relevant to the case at hand.

Finally, a good structure will be  MECE  or mutually exclusive and collectively exhaustive.

This means the framework will break down the market or population being analyzed into segments that include every part of the whole (collectively exhaustive), and each segment of the market or member of the population will show up in one and only one category without overlap (mutually exclusive). 

For example, if you divide the target market for a retail product into segments by age, these segments would be MECE:

The categories 15-25, 20-30, 27-35 would not be MECE because people could be counted twice. 

Case Interview Analysis

In the analysis phase of your case interview example, you’ll ask questions to get the information you need to solve the client’s business problem. Your questions will likely lead you to one of the 4 types of analysis that are common in consulting interviews: market sizing, brainstorming, quantitative reasoning (case math), or reading exhibits. 

No matter which of these types of analysis comes up, there’s a 4-step method that ensures you can crack the case. 

This 4-step method is:

The data you ask for will depend on the case interview question you’re solving. For example, if the question is about profitability, you’ll need to know about the client’s finances: dig into revenues and costs. 

For example, if you find that the client’s revenues are flat while their costs have been rising, you’ll know that the problem is in the cost structure and that you’ll need to examine costs more closely.

Next, provide insight. As you examine costs further, you’ll find out why they’ve grown faster than revenues. 

This insight will naturally lead to the next steps. What does the client need to do to get costs under control and fix their profitability problem? 

You may need to go through this 4-step method a couple of times, focusing on different aspects of the client’s business problem. 

Once you’ve examined and developed insight into all key aspects of the problem, your next step will be to conclude the interview with a recommendation for the client.

Case Interview Conclusion

At this point, you’ve hopefully cracked the case and are ready to present your recommendations to the client (your interviewer). 

The best way to do this is to use the 5R approach:

While most candidates will address their recommendations and possibly the reasons for their recommendations, few will hit all these points. 

In particular, outlining risks and further ways you can help the client will differentiate you from other candidates and help you to advance  to the second round of interviews or get the offer.

14 Best Case Study Questions to Ask Your Top Customers

Illustration Of Case Study Questions

If you want to show interested leads that you can put your money where your mouth is, case studies are a good way to go. They’re a valuable form of content that can even be used as lead magnets under the right conditions, and they have a singular purpose: To show how your clients achieved specific, significant results with your product or service. 

Knowing how to write a great case study is an important part of success, but there’s a part of the process that comes before that: Knowing which questions to ask, which you’ll determine when you’re preparing for a case study interview. 

The questions you ask can make the difference between a case study that feels like it’s been churned out by a low-quality AI machine compared to one that feels actionable, engaging, and high-stakes to your readers. 

In this post, we’re going to go over the 14 best case study questions to ask, along with discussing some tips to improve the results you’ll get. 

How to Structure Your Case Study Questions

Before we dive in, we want to talk about how to structure your questions in the interview.

In this post specifically, we’re going to look at individual questions you should ask around pointed topics, like about the client’s brand, solutions they’ve tried already, and their results. 

It’s best to stick close to the progression outlined here because it will give you the basic information you need at every level of the case study interview . You can’t ask what solutions they’ve tried before when you don’t even understand their brands’ needs. 

And keep in mind that when you’re asking users to provide specific information about a topic up front, they’ll often reference it later, strengthening the overall case study and sometimes encouraging them to share information they may not have thought to share otherwise. 

That being said, let’s go ahead and start to dive in to the best case study questions you should ask. 

Questions About Their Brand 

The best case studies will have some information about the brand they’re featuring and not just about how the brand uses their product. Information about the brand size, industry, and unique selling propositions (USPs ) can all play a valuable part in building a strong case study. 

Case Study Questions About Branding

These are a few important case study questions to consider asking about branding: 

1. Can you tell us a little bit about your brand? 

This is a great way to start the interview off strong. Ask the client to tell you about the brand, plain and simple. See what they have to say; they may share information about their product or service, how they fit into their industry, what differentiates them, and more. 

Leaving this first question relatively vague and open-ended helps them feel more comfortable while giving you some good ideas for where to go. 

If they’re stumped, ask them to provide a brief description of what their company does.

2. Can you tell me about your business’s structure, including industry, company size, or years in business? 

While this may feel technical, it can be exceptionally valuable to readers of the case study to help them relate or get a good understanding of who is using your products. 

3. An industry-relevant question 

SaaS tools that help with ad management may ask clients about their total monthly ad spend, for example. An eco-friendly company may ask clients what their “green goals” are or their previous carbon emissions. 

Think about what would benefit you to have in the case study, and ask it here if possible. 

Questions About Their Challenge & Pain Points 

We know that all great case studies will highlight the challenges that clients have before finding your product or service as their solution, exacerbated by key pain points. 

It’s so important to get enough information that these challenges feel real and significant in the case study; if you neglect to explain why a challenge was an actual obstacle, it can come across as seeming trivial. That can make your solution seem trivial, too.

Case Study Questions About Challenge And Pain Points

These are the best case study questions to ask for this stage of the interview.   

4. What were the challenges you needed to solve before finding our product? 

This is a specific, pointed question, which helps make it effective. 

If I ask my content marketing clients this question, for example, they might say, “we didn’t know how to create content that ranked well” or “we needed help creating content at scale.” 

You can dive deeper by asking pointed questions about their key problems, which brings us to the next question. 

5. Why did this challenge have such a significant impact on your business?

This is the golden ticket right here, because it’s about pain points. 

Say you’re selling marketing services, and the client’s challenge is that they wanted help with lead generation. 

The pain points of “organic channels were too slow in driving customer acquisition, and our churn rates were eviscerating our client numbers” or “we tried to run ads ourselves but ended up losing hundreds of dollars to no avail.” 

Wasted money. Bleeding clients. Too-slow organic channels. These are pain points that make the case study feel real, and that other customers will connect to.  

6. What other solutions had you tried before and why didn’t they work? 

While it’s best to skip out on trash-talking competitors in the case study, asking this question during the interview can give you valuable context and a lot to work with. 

If, for example, I’m a weight loss coach, my clients may have tried the keto diet and Weight Watchers to no avail. Knowing that the keto diet made them feel queasy and that they found the point-tracking Weight Watchers to be too much work can be useful information for the study, even if you don’t ever name the alternatives.

These are pain points in their own right, and can be utilized like the following: 

 “The client had tried different solutions before but found that the diets either made them sick or were too much work to maintain.” It positions your solution to be the winning option. 

Questions About How They Discovered You 

While it may seem irrelevant, information about how customers discovered you and why they decided to work with you can actually become compelling parts of a case study— even if only mentioned in brief. 

Here’s an example of how you can use this information in the case study: 

“We found Breadcrumbs after our business partner mentioned it to us, and after reading about their easy-to-use interface and accessible lead scoring, we decided to give it a try.” 

You’ve got social proof (business partner referred them) and a promo for a unique feature that made them convert. 

Case Study Questions About How They Discovered Your Product

Here are the case study questions you can ask to get this information:

7. How did you find out about our brand? 

It’s a simple question, and it will likely be a simple answer. Nice and easy. 

8. What made you decide to try our product over other solutions? 

This essentially gets the customer to sell your product back to you, which is phenomenal. And someone reading the case study might think, “They’re right; I’ve also looked for a lead scoring tool with a great interface, I’d try that.” 

Questions About How They Used The Product or Service 

This will likely be one of the meatier parts of the case study interview because this is where some of the actionable information comes into play. How did your clients use your product or service, what steps did they take, and how can others use this to replicate the eventual results we’ll discover? 

Case Study Questions About How They Used Your Product Or Service

These are the case study questions to ask: 

9. Which specific products and product features did your team use? 

Say you’re selling invoicing software to small businesses. Not all clients will use every feature.

Graphic designers, for example, may take advantage of project estimates for upfront deposits more than a copywriter who only works for flat fees. That copywriter, however, might be more likely to use invoice templates for retainer clients or automated billing features. 

Ask about the products and services the team used. 

10. How did your team use our products and services to meet their needs? 

You know what products or services were used, but now it’s time to ask how they were used.

Project estimates, for example, allowed graphic designers to send more professional-looking invoices to clients, who could pay upfront deposits through credit card, check, or bank deposit. This helped that designer weed out clients who had no intention of paying and gave them the funds they needed to secure the supplies to begin working.

And for the copywriter who used automated billing, it saved her an exceptional amount of time and ensured she got paid on time because she sent those invoices on time. 

11. How was your experience? 

Was the SaaS tool user-friendly? Did your clients take advantage of a free demo program or the option to have an account manager get their entire account up and running?

Ask about their specific transition process using the tool and what made the experience a more positive one. 

Questions About Their Results 

Last but not least… the results. Believe it or not, some case studies skip this part of the interview, but you definitely want to include hard, quantifiable data in as many case studies as possible. 

Case Study Questions About Their Results

12. What end results did you get after using our product? 

Ask for the results your clients achieved. If they’re comfortable sharing the information, ask for KPIs. 

How did using our social media marketing software increase message response rates? 

How did our marketing service improve lead generation efforts, and customer acquisition costs? 

How did our lead scoring software reduce the contact-to-close period for leads or increase the overall financial value of leads acquired? 

Be as specific as the client will allow. The more definitive the data you can share, the better. 

13. What impact did these results have on your business? 

While this may seem self-explanatory, this is a great final question that again helps the impact of your product or service really stand out.

We saw customer satisfaction increase and sales go up by about 15% by improving message response rates on social media. 

Or, by getting more leads at lower costs, our business was able to reinvest those accelerated profits into additional campaigns to scale exponentially at an unprecedented rate, and now we’re opening two new branches. 

This can be a combination of data-focused or story-driven impacts. Either (or both!) works well. 

14. Is there anything else we should know? 

Anything else you want to share? This is a short but powerful question, and while some clients will say, “nope, that’s it,” you may be surprised what some other people share with you. 

There may be something they’ve been excited to talk about that hasn’t come up in the questions yet, or something may pop into mind to elaborate on something you’d discussed earlier.

Give them the floor, and see what they have to say. 

Final Thoughts 

If you’re going to take the time needed to conduct and write up a case study (both your own time and the client’s), you want to get it right. Coming prepared with a list of strong case study questions can help you create content that will be highly effective at generating leads and converting customers for a long time to come.

33 Case Study Questions for Customer and Client Interviews

When selling your product or service to prospective customers, you make a stronger case when you can show concrete results. This is where a case study comes in. A case study strengthens your sales pitch by showing firsthand results. You can boost your case studies by interviewing previous customers and asking them to share how they benefited from your business. Interview your loyal customers using the following questions to build strong case studies you can share with new prospective clients.

two women speaking at a table near a large window

What is a Case Study?

A case study is a detailed report that showcases how your product has benefited previous clients. It is a way to show firsthand how your product or service can benefit potential new clients. Case studies help you build trust with new clients — 88% of whom trust online customer reviews and ratings. Conversely, only 14% of customers trust advertisements.

Asking the right types of questions to your previous customers will help you better craft your final case study. Since you will be writing these studies with new clients in mind, drafting your questions beforehand will give you the right information to highlight how you have previously solved similar client issues in the past.

How to Write Case Study Questions

This section offers an outline of sections that should be included in your final case study and sample questions to ask of your clients.

Start With the Backstory

Before writing your case study questions, determine why you are writing it. Outline the major problems you intend to highlight and create questions that will allow you to articulate how you solved them. The following section includes case study question examples you can use to conduct your client interviews, but you can modify them based on your goals.

When interviewing your previous clients, first introduce them to your audience by including some background information on their company. Next, set up the case study by presenting the initial problem.

Establish Your Relationship

After setting up the problem and why it was significant to your customers, ask them to define their relationship with your brand. If you are interviewing repeat customers, ask them how they discovered your business, why you were their chosen solution, and what's kept them coming back. If you are interviewing a first-time client, ask what drew them to your business over another.

Some questions can include:

Have Them Demonstrate Your Product

Once you have set up the initial problem and delved into how your client chose you to solve it, you can get into the details of the actual case study. Ask specific questions about how your client used your product or service.

Be detailed. These answers will help you draft a case study that resonates with prospective buyers who are facing the same issue.

Outline the Product’s Benefits

This section of your interview will delve into the actual solution and its results. Use this section to ask about specific outcomes and metrics the company used to track successes.

Wrap Up the Interview

At the end of the interview, ask some general business case study questions relating to customer satisfaction and relationship management. You can use these to conclude the case study. This section of the interview is also likely to generate some potential customer quotes you can use in your marketing materials .

How to Ask Your Clients for an Interview

If you have been in business for a while, you probably know your best advocates. Think about your top customers, and start by asking those who are the most likely to promote your business. If you know a client who often refers customers to you, ask them for a specific example of how your company helped them solve a problem.

You might draw a blank when asked to identify your best advocates. In this case, talk to your sales team or your project managers to see if they know of any potential customers who would be happy to share their success stories.

Consider your customers’ time. Don’t approach them for an interview in the middle of a busy season or if they have had a recent issue with your company. Get familiar with your selected clients and how they intended to use your product so you have some background information before starting the interview.

Finally, write a personalized request. Don’t send out a form email requesting case studies. Make your requests relevant to each potential interviewee so they know they are valued customers.

How to Write the Case Study

Instead of taking notes during the interview, take a recording on your phone or a portable recording device and transcribe it when you’re done. You can take minor notes as you go along, to help when you go back to transcribe. This way you can be more engaged in the interview and follow up on interesting information that might pop up. Be sure to check that your recording hardware or software is working ahead of time, to ensure you don't lose valuable information during the interview.

The case study questions listed above are arranged as an outline of a typical case study. Start by introducing the company and the problem they were trying to solve when they sought out your business. Next, explain the process of how they used your product to solve their problem.

End the case study with numbers and statistics demonstrating how you helped the business successfully solve its problem. Make sure you get specific numbers and figures to illustrate your clients’ successes. If you don’t get them during the initial interview, follow up with a phone call or email.

Sample Case Study Questions and Answers

These sample case study questions and answers demonstrate how to extract information from your interview and turn it into an engaging business case study that is interesting and informative.

This case study from Switch, a digital marketing agency, details how the company was able to help a client improve its return on investment (ROI) on search and Facebook ad campaigns by moving them from their in-house marketing team.

The case study starts with an impressive statistic — the company improved its ROI on search ads from 1.2x to 19x in a short time period. The case study breaks this statistic down for potential leads who might not be familiar with marketing terminology, indicating that its client was able to increase sales without spending more on search engine ads.

While the actual case study interview is not published, a sample question and answer that would have generated this data could be:

This case study goes into detail about how Switch worked with its clients to refine the Facebook and search ad strategy, ending with impressive results.

Rogers Communications

Rogers Communications featured this case study detailing how its client Brampton Caledon Community Living (BCCL) used the company’s cloud-based mobile phone system to better service clients. This case study is simple, laid out with headings like “Challenge” and “Solution.”

Rogers Communications pulled relevant quotes from the client and included them in text boxes throughout the study to break up the text. Rogers also included direct quotes from personnel at BCCL, making a strong case for its product. While it doesn’t offer hard numbers like the previous example, it does include a quote detailing how the cloud-based system has improved the work environment.

Again, the interview for this case study is not included in the example, but it does include the answers as client quotes.

Best Practices for Conducting A Business Case Study Interview

When you’ve found client advocates who are willing to talk to you about how your company led them to success, draft your interview questions. Keep these best practices in mind.

Be Prepared

Being well-prepared for your interview is the best way to ensure its success. Before meeting with your client, learn what you can about the client so you can flesh out the case study. Conduct a mock interview to prepare. Talk to your sales team or the client’s specific project manager for details to better understand the client and what they were facing when they hired your company or purchased a product.

Ask Open-Ended Questions

Structure your questions so the interviewee has to give detailed answers. If you limit your interview to "yes" or "no" questions, it can be hard to gather enough information to write your case study. Open-ended questions let your client get into the specifics surrounding the study.

Do a Deep Dive

One reason you should record your interviews and transcribe them later is so you can focus on the client’s answers. Often, information will come up in an answer to one question that will prompt you to ask a follow-up question. Recording your interview lets you deviate from your prepared questions to get a more robust analysis of the case.

Getting Started on Your Case Study

Case studies are a great marketing tool for building credibility. They give prospective clients a better understanding of how you work and how you can provide alternative solutions for key issues. But the key to writing a good case study is to start with a quality interview.

You have the tools needed to draft powerful questions. So start the process by looking through your list of past clients and determining who would be the best to interview. Develop a thorough understanding of their situation and their history with your company, and then conduct your interview.

After your first few case studies, you'll be confident on how to best structure questions and refine your interviews to get the best information. Soon, you will be crafting detailed and engaging case studies to best market your business.

P ertanyaan semacam ini bukan berarti jebakan, melainkan interview er ingin melihat kemampuan analisis dan problem solving -mu.
