We have a library of 15 to 40 cases that cover the full spectrum of product management challenges. Watching mock interviews and expert feedback is the best way to learn how to approach these cases.
This course section is designed to help you learn from real PM interview cases and expert mock interviews. The best way to prepare for product management interviews is to see how others approach case questions — what frameworks they use, how they prioritize, and how they communicate their thought process.
You will watch videos of industry experts like Bharat Maddali, Ashutosh Mangal, and Nagendra Gururaj conducting mock interviews and giving detailed feedback. Their insights will show you what interviewers look for and how to avoid common mistakes.
The role of case studies in PM interview preparation
Case studies are the core exercise in most PM interviews. They simulate real-world problems you will face as a PM — from defining product goals to prioritizing features, analyzing metrics, or designing new experiences.
The cases we cover come from a broad library of 15 to 40 curated problems that represent typical product challenges. This range is more than enough to prepare you for the breadth of questions you will encounter.
Each case challenges you to:
- Understand the problem context quickly
- Identify the user and business goals
- Apply first principles thinking to generate solutions
- Prioritize features or actions based on impact and feasibility
- Communicate your reasoning clearly and confidently
What makes a strong case study presentation?
When you prepare a case study presentation for an interview or an assignment, aim for clarity and structure. Here is a practical outline I recommend:
| Slide | Content |
|---|---|
| 1 | Research — what do you know about the problem, users, and market? |
| 2 | Prioritization — what is the most important problem to solve first? |
| 3 | Solution outline — what do you propose building and why? |
| 4 | Wireframe or flow — how does the user interact with the solution? |
| 5 | Metrics and next steps — how will you measure success and iterate? |
This is a starting point. Depending on the case, you may add or remove slides, but these five cover the core thinking.
Reach out to current PMs or peers and ask for feedback on your slide deck. Practicing live mock interviews with mentors or peers will also improve your confidence and polish your delivery.
Common PM interview case examples
Our case library includes diverse scenarios from Indian and global contexts to cover different skills:
- Build a 1-year roadmap for OYO to improve NPS (strategic planning, business process improvement)
- Design a product for children aged 3–10 to teach design thinking (user research, systems development)
- Investigate a 20-30% drop in Netflix’s average watch time over 3 months (data analysis, hypothesis testing)
- Define goals and metrics for Google Pay and propose improvements (goal-setting, metric system design)
- Analyze Myntra’s 10% traffic increase and 12% conversion rise to assess sales impact (metrics, business impact)
- Expand GroMo’s product to a new user group like housewives (market segmentation, feature design, release planning)
- Develop a video course feature/platform within an existing product (technical systems design)
- Solve a voting turnout decline through technology as a PM in an NGO (social impact, product ideation)
- Improve discovery goals and success criteria for Google Play Store app (product vision, metrics)
- Productize a hypothetical teleportation technology from both product and business perspectives (innovation, go-to-market)
These cases help you sharpen your ability to think across product strategy, user experience, analytics, and business outcomes.
How mock interviews with expert feedback accelerate learning
Watching mock interviews conducted by experienced PMs is invaluable. You see real-time thinking, how the candidate handles pressure, and how the mentor guides and critiques.
Here is how these sessions add value:
- Highlight mistakes — interviewers point out when candidates miss the core problem or get lost in details.
- Teach frameworks — mentors share mental models and methods to structure answers effectively.
- Model communication — you learn how to narrate your thought process clearly and confidently.
- Showcase prioritization — mentors emphasize the importance of making trade-offs and saying no.
- Provide encouragement — mentors share what good looks like and how to improve iteratively.
Crafting your own approach to case study questions
When faced with a case question in an interview:
- Clarify the problem: Ask questions to understand the context and constraints.
- Define success: What metrics or outcomes indicate success for this product or feature?
- Segment users: Identify key user groups and their distinct needs.
- Prioritize: Choose the highest-impact problems or features to address first.
- Design solutions: Propose clear, feasible solutions aligned with your prioritization.
- Measure impact: Suggest metrics and experiments to validate your approach.
- Communicate clearly: Narrate your reasoning step-by-step.
This approach demonstrates structured thinking, user focus, and business impact awareness — the core of PM interviews.
Field exercise: Analyze a sample PM case study
Pick one of the following cases from the library:
- Netflix’s 20-30% drop in average watch time
- GroMo expanding to housewives
- Google Pay goal and metric definition
For your chosen case, write down:
- The key problem statement in one sentence
- The primary user segments affected
- Three hypotheses for why the problem exists
- Two potential solutions prioritized by impact
- The metrics you would track to measure success
If you have a friend or mentor, discuss your answers and get feedback on your reasoning and communication.
Judgment exercise: Prioritizing case study content under time pressure
You are interviewing for a PM role at a Series B Indian startup. You have 30 minutes to prepare a 5-slide case study presentation on expanding the product to a new user segment: housewives in tier-2 cities.
The call: What should your five slides focus on, and how do you prioritize content to fit the time and audience?
Your reasoning:

Meeting scene: Mentor feedback on a candidate’s case study approach
Mock interview feedback session with mentor Nagendra Gururaj
Candidate: “I included 12 features in my roadmap because I wanted to show breadth.”
Mentor Nagendra: “That’s a common mistake. Interviewers want depth and prioritization, not a laundry list. Which three features move the needle most?”
Candidate: “I think onboarding improvements, referral program, and new payment options.”
Mentor Nagendra: “Great. Focus your narrative on why these three solve the biggest user pain points and how you will measure success.”
Candidate: “Understood. I’ll trim the slides accordingly.”
Mentor Nagendra: “Remember, the actual job in an interview is to make decisions clearly, not to please everyone with every feature.”
The trap is confusing feature quantity with product impact.
