"Walk me through one portfolio project you personally drove from problem definition to launch. I’d like you to focus on a real product surface — for example Facebook, Instagram, Messenger, WhatsApp, or Meta Quest — and explain how you framed the problem, made key design decisions, handled trade-offs, and influenced partners to get it shipped. Be specific about where the requirements were ambiguous, what you prioritized, and what happened after launch."
This question tests whether you operate like a product designer who can lead, not just produce polished screens. At Meta, designers are expected to shape the problem, align cross-functional partners, make principled trade-offs under time pressure, and maintain ownership through launch and iteration. Interviewers are listening for how you navigated ambiguity, balanced user needs with business and technical constraints, and influenced PM, engineering, research, and content partners without relying on formal authority.
A strong answer uses one concrete project with clear stakes, timeline, and your specific role. The best responses show structured thinking, a few pivotal decisions and trade-offs, evidence of influence or conflict resolution, and a measurable launch outcome — plus one thing you learned and would do differently next time.
