A product manager case study interview is a 15 to 45-minute interview in which you are placed in a hypothetical business situation and asked to strategize, design, improve, or grow a particular product. It is a special type of interview question used to evaluate candidates in all product roles.
A product manager case study interview begins with the interviewer giving you a broad, ambiguous business or product question. Examples of questions you may see include:
Typically, companies will ask these questions for a particular product that the company sells. However, companies may use other, more well-known products instead if their products are too technical, complicated, or obscure.
There are four major types of product manager case study interview questions: product design, product improvement, product growth, and product strategy questions.
Product design case study interviews ask how you would design a particular product or service. Examples of product design case study questions include:
Product improvement case study interviews ask how you would improve an existing product or service. Examples of product improvement case study questions include:
Product growth case study interviews ask how you would grow sales for an existing product or service. Examples of product growth case study questions include:
Product strategy case study interviews ask how you would make strategic business decisions regarding a product, service, or for the company overall. Examples of important strategic decisions include:
Companies use product manager case study interviews to simulate problems that product managers face daily, evaluate how candidates think, and predict on-the-job success.
1. Simulate challenges that product managers face daily
Product manager case studies closely simulate the problems that product managers face in their role. By presenting candidates with real world scenarios, companies gain valuable insight into how candidates react when faced with a challenging, ambiguous, or broad problem.
These simulations provide a glimpse into how the candidate may actually perform as a product manager. Through product manager case study interviews, companies assess candidates' readiness to tackle the diverse array of challenges inherent in product management roles, ensuring they possess the necessary skills and mindset to excel.
2. Evaluate how candidates think
Conducting product manager case study interviews allows companies to evaluate not only what candidates know, but also how they think. By presenting candidates with hypothetical scenarios or problems to solve, companies gain insight into their thought processes, analytical abilities, and approach to decision making.
This assessment goes beyond assessing technical knowledge or specific skill sets, focusing instead on candidates' problem solving capabilities, creativity, and critical thinking skills.
3. Predict on the job success
Product manager case study interviews play a pivotal role in predicting candidates' on-the-job success by providing a glimpse into their ability to apply their knowledge and skills in practical contexts.
By evaluating candidates' performance in simulated scenarios relevant to the role, companies can gauge their potential to drive product success, collaborate with cross-functional teams, and deliver tangible outcomes.
Candidates that do well in product manager case study interviews signal a readiness to tackle the challenges of product management, minimizing hiring risks and increasing confidence in their ability to contribute meaningfully to the company’s objectives.
Product manager case study interviews assess: problem solving skills, communication skills, product vision and strategy, creativity and innovation, and industry knowledge and expertise.
Problem solving skills
Product manager case study interviews quickly assess a candidate's problem solving skills. These case studies simulate real world challenges, allowing hiring managers to observe how candidates approach complex problems, break them down into manageable components, and develop viable solutions.
By evaluating a candidate's ability to think critically, creatively, and analytically, companies gain insight into their capacity to navigate the different challenges faced as a product manager.
Communication skills
Effective communication is a crucial skill for product managers who must interact with diverse stakeholders across an organization. Product manager case study interviews provide an opportunity to evaluate a candidate's ability to articulate their thoughts clearly, convey complex ideas succinctly, and engage stakeholders effectively.
Strong communicators can convey product vision compellingly, aligning stakeholders around a shared objective. They can build rapport and trust, facilitating seamless teamwork and driving successful product outcomes.
Product vision and strategy
Central to the role of a product manager is the ability to formulate a compelling product vision and strategy. Product manager case study interviews allow companies to assess a candidate's capacity to think strategically, envision the future trajectory of a product, and develop a product roadmap.
Through articulating a clear product vision, defining measurable objectives, and outlining a coherent strategy, candidates demonstrate their strategic acumen and ability to translate abstract concepts into actionable plans.
A strong understanding of market dynamics, customer needs, and competitive landscape informs a robust product strategy, enabling candidates to devise innovative solutions that resonate with target audiences and drive growth.
Creativity and innovation
In an increasingly competitive landscape, companies seek product managers who can infuse creativity and innovation into their product development process. Product manager case study interviews provide a way to evaluate a candidate's ability to think outside the box, challenge conventional wisdom, and generate novel ideas.
Candidates are tasked with solving hypothetical problems or brainstorming innovative features, offering insights into their creative problem solving skills and ability to push boundaries.
By encouraging candidates to explore unconventional solutions, companies identify individuals who can drive product differentiation and deliver transformative products that captivate users and outpace competitors.
Industry knowledge and expertise
A deep understanding of the industry landscape is essential to being a great product manager. Product manager case study interviews allow companies to assess a candidate's industry knowledge, domain expertise, and familiarity with relevant market trends and technologies.
Candidates are expected to demonstrate their understanding of industry dynamics, customer behaviors, regulatory considerations, and emerging technologies that may impact product development.
For each type of product manager case study interview question, we’ve detailed the exact steps you should follow to deliver an outstanding answer and impress your interviewer.
When asked how you would improve or design a product, resist the urge to list the first few ideas that come to your head. Instead, follow this systematic approach to demonstrate to the interviewer how you think about the product improvement and design process.
There are six main steps to solving product design or improvement case study interviews.
1. Define the goal
It is difficult to design or improve a product unless you have a specific and clear goal in mind. What are you trying to achieve?
The way you design or improve a product will change drastically depending on what you are trying to achieve. So, it is important that you confirm with the interviewer what the explicit goal is.
Are you trying to increase the number of monthly users? Are you trying to increase revenue per user? Is the goal to increase customer engagement? All of these different goals have drastically different solutions.
2. Identify a customer segment to target
The goal of this step is to focus and narrow down the scope of product improvement or design to one specific customer segment.
There are two reasons why you should do this.
One, customers can have a wide range of needs and preferences. Trying to improve or design a product that would benefit every single customer can be very challenging.
Two, by focusing on a specific customer segment, you can develop product improvements and designs that are more specific and tailored to the segment’s needs. You will avoid suggesting product ideas that are generic and not impactful.
Therefore, start by listing the different customer segments that come to mind. Select one segment and provide a reason why you are focusing on that segment.
You might choose a segment because they are the largest segment or you might pick a segment if their needs are underserved.
3. Select a pain point to focus on
Brainstorm a list of pain points for the selected customer segment. These can be unmet customer needs or features of the product that customers find frustrating, time-consuming, or difficult to use.
Select one pain point and provide a reason why you are focusing on it. You might select a pain point if it is the most common, the most severe, or the most practical to solve for.
4. Brainstorm product improvements or designs
Now that you have chosen a pain point to focus on, brainstorm a list of different ways to solve for that pain point.
Try to have at least 3 – 5 different ideas. Include a few ideas that are creative and unconventional. This demonstrates originality and out-of-the-box thinking.
If you are having difficulty generating enough ideas, you can use the SCAMPER framework to help you brainstorm ideas.
SCAMPER stands for substitute, combine, adapt, modify, put to another use, eliminate, and reverse.
5. Assess which idea is best
For this step, create a list of criteria to assess your different ideas. Common criteria include:
Select the most important criteria based on the nature of the product and the pain point. Afterward, assess each of your product ideas based on the list of criteria you have developed.
You can assess your ideas either quantitatively or qualitatively.
The most common way to quantitatively score ideas is to give them one, two, or three points for each criteria. The idea that has the highest total number of points will be chosen.
Some criteria may be significantly more important than others. In this case, you can consider weighting the point values differently. For example, if the magnitude of impact is by far the most essential criteria, you can double the point value. Each idea will be given two, four, or six points for this criteria.
In assessing your ideas qualitatively, talk through how each idea performs on the criteria you have selected. Choose the improvement or design that has the most positive assessment overall.
6. Explain how you would test this
After you have selected your best idea, suggest how you would test whether this product improvement or design works. Specify what metrics you would want to measure to determine this.
This step is not always necessary, but it demonstrates to the interviewer that you can think like a product manager. Product roles involve a lot of testing and iterating on features and improvements.
A/B testing is the most common way to test a new product feature or design. In A/B testing, you compare the performance of two variations of a product against one another.
Typically, you would run an experiment in which one group of customers is given the original or older product and another group of customers is given the new and improved product.
After defining the right metrics to measure performance, you can determine which version of the product performs better.
They key to solving product growth case study interviews is to have a comprehensive growth framework where you can systematically list and talk through all of the major ways to grow.
A case study framework is a tool to structure and break down business problems into smaller components.
You can think about growth through two major categories, organic growth and inorganic growth. These two categories form the foundation of our growth strategy case framework.
Organic growth
The most common type of growth that companies pursue is organic growth, which is growth driven by expanding output or engaging in internal activities. In other words, the company is growing through its own capabilities and efforts.
Organic growth can be segmented into growth through existing revenue sources and growth through new revenue sources.
Growth through existing revenue sources is either driven by an increase in quantity of units sold or by an increase in average price per unit sold.
To increase the quantity of units sold, a company can:
Remember that changing prices will impact quantity of units sold, so it is important to look at the net effect price changes have on revenue.
To drive growth through new revenue sources, a company can:
Inorganic growth
Inorganic growth, on the other hand, is growth driven by acquisitions, joint ventures, or partnerships.
The first way that a company can grow inorganically is by acquiring another company. This gives the acquiring company all of the revenue that the acquisition target generates. In addition, there may be revenue synergies that the acquiring company can realize.
Acquiring a company gives the acquiring company access to the acquisition target’s distribution channels, customers, and products. The acquiring company may be able to increase revenues by cross-selling products, up-selling products, or bundling products together.
In a joint venture, two or more companies enter a business arrangement in which they pool together resources and share risk in accomplishing a particular task. Each company in the joint venture is responsible for profits, losses, and costs associated with the project.
A partnership is an association between two or more companies that provides some kind of benefit to each partner. This is slightly different from a joint venture because in a partnership, companies do not necessarily have to combine resources or efforts. They just need to be associated with each other.
When answering a product strategy question, you should create a framework to structure your thoughts rather than saying the first few ideas that come to mind.
As a reminder, a framework is a tool to structure and break down business problems into smaller components. The answers to the questions in your framework will help you answer the overall product strategy question.
There are six steps to creating outstanding frameworks to answer product strategy case study interview questions.
1. Memorize eight robust business categories
There are eight broad business categories that are frequently looked at when making product strategy decisions.
By memorizing these eight categories, you’ll have an easier time creating an outstanding framework rather than having to create frameworks from scratch each time.
These eight business categories are:
For each of these broad business categories, we’ve included a few potential topics to give you a sense of what each category means or encompasses.
You will only need to memorize the eight broad business categories. You do not need to memorize all of the potential topics under each.
2. When asked a strategy question, ask for a few minutes to structure your thoughts
When given a product strategy case study interview question, ask for a few minutes to structure your thoughts. Almost every time, the interviewer will give you time to develop a framework.
3. Mentally run through the eight business categories and select the 3-4 most relevant ones
Next, mentally run through the eight business categories that you’ve memorized and select the 3-4 most relevant ones.
3-4 is the ideal number of categories for your framework. It is the right balance of comprehensiveness and simplicity.
Any fewer than 3-4 categories and your framework may not be comprehensive enough. You may be missing critical questions that are necessary to answer the strategy question.
Any more than 3-4 categories and your framework becomes too large and complicated. You also risk having redundancies in your framework.
4. If you are unable to select 3-4 relevant business categories, think of your own business categories to include
If you are unable to get 3-4 categories in your framework after running through the memorized list of business categories, then it is time to think of your own business categories to include.
This happens more commonly when given atypical or unusual product strategy case study interview questions.
Remember, the eight broad business categories you memorized work for the vast majority of strategy questions, but does not cover all of them.
5. Add specific questions under each business category you’ve selected
Once you have identified the 3-4 major categories in your framework, add sub-bullets or questions underneath each of them to add more detail.
6. Walk the interviewer through your framework and answer
When you’ve finished developing your framework, walk your interviewer through it.
At the end of each major category, give your opinion on which answer or recommendation it supports.
Once you’ve walked the interviewer through your entire framework, you should have an overall answer to the product strategy case study interview.
We’ve compiled a few product manager case study interview examples with complete answers below. These examples should give you a good sense of what outstanding answers sound like.
Product Manager Case Study Interview Example #1
How would you improve YouTube?
For this question, I’ll assume that the goal of the improvement is to increase user engagement on the platform, which can be measured as the amount of time a user spends on YouTube.
First, I’ll think through the different customer segments and pick one to focus on. Three customer segments immediately come to mind:
Out of these segments, I will focus on entertainment seekers because this segment probably makes up the most significant portion of YouTube’s user base.
Next, I’ll identify a pain point to focus on. Entertainment seekers have a few different pain points:
Among these pain points, I’m going to focus on the tedious video discovery process because it is probably the biggest pain point for these users.
Now, I will brainstorm a few ideas on how to make the video discovery process easier.
I will assess each of these ideas on their impact, user experience, and ease of implementation.
The first idea, recommending videos based on videos that friends have seen, would have minimal impact if the user does not have friends that use YouTube frequently.
Additionally, this idea does not change the user experience much because entertainment seekers would still need to decide whether to watch a recommended video. The upside of this idea is that it would not be difficult to implement.
The second idea, having a continuous, curated video feed, could have a tremendous impact. It removes the burden of decision-making from entertainment seekers because YouTube videos are automatically played.
The user experience is also an improvement because the user only needs to click a skip button when they are bored. The downside of this idea is that developing a good algorithm could require substantial investment.
The third idea, sending a curated playlist to the user each day, would have some impact on users. The decision making process is slightly simplified because the user receives a shorter list of videos to choose from. However, once the playlist is finished, the user would still need to look for more videos on their own.
Additionally, the user experience is not ideal. Getting an email or notification every day can be annoying. The upside of this idea is that it is the most straightforward to implement.
Based on my assessment, the continuous, curated video feed seems to be the most promising.
To test this idea, I would develop a minimal viable product and use A/B testing to assess the performance of this feature.
One customer group would be given access to this feature while another customer group would not. I would measure the difference in minutes of video consumption between the two groups for one month to determine if user engagement has increased.
Product Manager Case Study Interview Example #2
How would you design an alarm clock for the blind?
For this task, let’s assume that the goal is to design an alarm clock that works reliably in waking up the user and is as easy to use as possible.
Additional alarm clock functionalities, such as checking the weather or listening to the radio, will not be considered.
The customer segment has already been defined, the blind.
There are four use cases that we need to design for:
For each of these use cases, we can brainstorm a few potential ideas and evaluate the pros and cons for each to decide which design is optimal for our goals.
To set an alarm:
To check if the alarm has been set:
To wake up the user:
To check the time:
Based on this, it seems that a voice assistant alarm clock that wakes up users with sound would be most suitable for our user.

Our company operates in the e-commerce space, primarily focusing on fashion and apparel. We're considering building a virtual fitting room feature that allows customers to virtually try on clothing items before making a purchase. How would you approach the decision of whether to invest in and build this new virtual fitting room feature?
There are four major factors to consider when deciding whether to build this new product feature:
1. Customer needs and preferences: Does this product feature resonate with customers?
2. Company capabilities: Does our company have the capabilities to develop this product feature?
3. Competition: Will developing this product feature help distinguish ourselves from competitors?
4. Profitability: Will building this new product feature be profitable?
Product Manager Case Study Interview Example #4
Our company manufactures smart home security systems and we’ve recently launched a new model with advanced AI-powered features. How do we increase our market share and customer base?
There are four major ways to increase our market share and customer base for this smart home security system product:
1. Develop targeted marketing
2. Form strategic partnerships
3. Enhance customer experience and advocacy
4. Engage with the community
There are several product manager case study frameworks that candidates may find helpful to be familiar with. These include the: 4P’s framework, design thinking framework, growth framework, product development lifecycle framework, and SWOT analysis framework.
4P’s Framework
The 4P’s framework is a fundamental marketing framework used to analyze and develop marketing strategies for products or services. It consists of four elements, each representing a different aspect of marketing strategy:
Design Thinking Framework
The design thinking framework is a human-centered approach to problem solving and innovation that is used to address a wide range of challenges and opportunities involved with product or service design.
It involves a structured process that encourages empathy, creativity, and collaboration to develop solutions that are user-centered, feasible, and viable. Here's how the design thinking framework is typically used:
Growth Framework
The growth framework, also known as the AARRR framework, is a framework used to analyze and optimize the various stages of the customer lifecycle. It is commonly applied in growth marketing and product management to drive user acquisition, activation, retention, revenue, and referral.
Here's a breakdown of the growth framework:
Product Development Lifecycle Framework
The product development lifecycle framework is used to guide the stages through which a product evolves from conceptualization to retirement. It outlines the key phases and activities involved in bringing a product to market and managing it throughout its lifespan.
Here's an overview of the product development lifecycle framework:
SWOT Analysis Framework
The SWOT analysis framework is a strategic planning tool used to identify and analyze the internal strengths and weaknesses as well as external opportunities and threats facing a business, product, or project.
SWOT stands for Strengths, Weaknesses, Opportunities, and Threats. Here's how each component of the SWOT analysis framework is used:
Below are our best ten tips for nailing your product manager case study interview:
1. Understand the Problem
Take the time to thoroughly understand the problem presented in the product manager case study interview. Break it down into its component parts, clarify any ambiguities, and identify the key objectives and constraints.
2. Ask Clarifying Questions
Don't hesitate to ask clarifying questions during your case study interview if anything is unclear or if you need more information to solve the case effectively. This demonstrates your ability to gather relevant information and ensure you're addressing the right issues.
3. Define Your Approach
Before diving into the solution, outline your approach to solving the problem. Walk the interviewer through the different steps you plan on taking. Describe the framework or methodology you'll use.
4. Think Creatively
Be creative and think outside the box when brainstorming solutions. Don't limit yourself to conventional approaches. Consider innovative ideas that could differentiate the product and provide unique value to users.
5. Prioritize Solutions
Not all solutions are created equal. Prioritize your ideas based on their potential impact, feasibility, and alignment with the objectives of the product manager case study interview. Focus on high impact solutions that address the most critical aspects of the problem.
6. Consider Trade-offs
Recognize that there may be trade-offs involved in any solution. Consider the pros and cons of each option, and be prepared to justify your decisions based on the trade-offs you've made.
7. Communicate Clearly
Articulate your ideas and solutions clearly and concisely. Use structured frameworks, visual aids, and data to support your arguments and make your reasoning transparent to the interviewer.
8. Collaborate Effectively
Product management is a collaborative role, so demonstrate your ability to work effectively with others. Solicit feedback from the interviewer, incorporate their opinions and perspectives, and communicate openly throughout the product manager case study interview.
9. Showcase Your Analytical Skills
Use data and metrics to support your decisions, solutions, or hypotheses. Analyze any data provided, draw meaningful insights, and use them to inform your decisions.
10. Practice product manager case study interviews
Like any skill, product manager case study interviews require practice in order to excel in them. Therefore, practice doing product manager case studies with a partner under timed conditions. Seek feedback from others to identify areas for improvement. Familiarize yourself with the products and services of the company that you are interviewing for.
There are six steps to preparing for product manager case study interviews: understand what a product manager case study interview is, learn the right strategies, practice a few cases by yourself, practice with a partner, practice with a current or former PM, and work on your improvement areas.
1. Understand what a product manager case study interview is
The first step to preparing for product manager case study interviews is to understand exactly what case study interviews are.
After you are familiar with what product manager case study interviews are, it is important to know what a great case study interview performance looks like. This will help you learn product manager case study interview strategies more quickly in the next step.
Before continuing onto the next step, you should be familiar with:
2. Learn the right strategies
Now that you have all the background information needed to succeed in product manager case study interviews, the next step is to learn the right strategies to build good interview habits.
It is much more efficient to learn the right product manager case study interview 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 read through our comprehensive product manager interview book. This book provides strategies on exactly what to do and say for over 10+ types of product manager interview questions, such as product design, marketing, estimation, strategy, execution, behavioral, and technical questions.
Before moving onto the next step, you should at least have strategies for the following types of product manager case study questions:
3. Practice a few product manager case study interviews by yourself
Once you have learned the right strategies, the next step is to practice doing a few product manager case study interviews by yourself.
When practicing product manager case study interviews, it is typically better to practice with a partner than to practice by yourself. Practicing with a partner better simulates the actual product manager interview experience.
However, when you are just starting out, it is better to do the first few cases by yourself because it’ll help you become familiar with the structure and format of product manager case study interviews much more quickly.
You also won’t have to waste time finding a partner and waiting for a time when they will be available to give you a mock interview.
4. Practice product manager case study interviews with a partner
The next step in preparing for product manager case study interviews is to practice doing cases with a partner. There are many aspects of case study interviews that you won’t be able to improve on unless you practice live with a partner.
When practicing product manager case study interviews with a partner, make sure that you are spending enough time after the mock interview to deliver feedback. Most of your learning and improvement will come from these valuable feedback sessions.
Do not move onto the next step until you have done at least 5 to 10 cases and are beginning to feel more comfortable with product manager case study interviews.
5. Practice with a former or current product manager
At this point, I strongly recommend asking former or current product managers to give you a mock interview. This will significantly help improve your performance on product manager case study interviews.
Doing a practice interview with a former or current product manager is highly beneficial because they know exactly what great answers sound like and can give you high-quality feedback to help improve the quality of your answers.
You can find former or current product managers among your friends, classmates, colleagues, and your broader LinkedIn network.
6. Work on your improvement areas
The last step in preparing for product manager case study interviews is to work on strengthening your improvement areas. Examples of common improvement areas or deficiencies include:
Try to work on improving one thing at a time. This will be much more effective than trying to improve on all of your weaknesses at once.
