What's Your Favorite Product, and How Would You Improve It?
Deceptively open. They're testing product judgment, user empathy, and prioritization - not your taste.
Interview prompt
What is your favorite product, and how would you improve it?
What interviewers evaluate
- Can you articulate WHY a product is good (for whom, what job, what makes it work)?
- Do you identify a real user pain, not a cosmetic nitpick?
- Do you propose improvements tied to user/business value and prioritize them?
- Do you reason about tradeoffs and how you'd measure the improvement?
A framework to structure your answer
- Pick & justify - choose a product you know deeply; state who it's for and the core job it nails.
- Mission lens - what is the product/company trying to achieve? Frame improvements against that mission.
- Identify gaps - find 2-3 genuine user pain points or unserved segments (not pixel tweaks).
- Prioritize - pick the highest impact-vs-effort improvement and justify the choice.
- Detail & measure - describe the improvement and the metric that would prove it worked.
Strong sample answer
Try structuring your own answer first, then reveal a strong worked example.
Common variants
- What product do you think is poorly designed, and how would you fix it?
- If you were the PM for [our product], what would you change first?
- What's a product you use daily that could be 10x better?
Pitfalls to avoid
- Praising a product without explaining who it's for or what job it does.
- Suggesting cosmetic changes instead of addressing a real user need.
- Listing improvements without prioritizing or justifying.
- Picking a product you don't actually understand deeply (follow-ups expose this).
- Ignoring the business: an improvement users love but that hurts the model is a weak answer unless you address the tradeoff.
Likely follow-ups
- How would you convince leadership to fund this over other roadmap items?
- What would make you kill this feature after launch?
- Who is the one user segment that benefits most, and why start there?
