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.

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?
