Favorite Product Deep Dive and UX Improvement Case
You will be assessed on product sense, UX judgment, and metrics thinking. Answer in three parts: a past UX-focused product experience, a product you love, and concrete improvements for that product.
Constraints & Assumptions
Choose a product you know well enough to discuss users, workflows, trade-offs, and metrics.
Use a real past experience for the first part, but anonymize sensitive details.
Propose improvements that are specific and testable, not generic feature wishlists.
Tie UX decisions to measurable user and business outcomes.
Clarifying Questions to Ask Guidance

Should the improvement focus on onboarding, retention, monetization, accessibility, performance, or engagement?
Are you looking for visual design critique, product strategy, or experimentation depth?
