Product Designer interview questions and what they really test
Design interviews probe your decisions: why this flow, why this tradeoff, how you validated it. These portfolio, critique, and whiteboard exercise questions reflect how strong design panels actually run.
Portfolio Deep-Dive
What the interviewer is testing: the real decisions, trade-offs, and outcomes behind one project.
- Walk me through your hardest project. What was the actual problem, and what did YOU decide?
- Show me a decision in that project you'd make differently now. Why?
App Critique
What the interviewer is testing: critiquing and improving a real product's UX with specifics.
- Pick a product you use daily and critique its worst flow. How would you fix it?
- What is one thing about Instagram's UX you'd change, and how would you validate it?
Design Exercise
What the interviewer is testing: an open design prompt: user, flows, trade-offs, edge cases.
- Design a check-in experience for a busy airport for elderly travelers. Flows and trade-offs.
- Redesign the alarm/clock experience for shift workers. Edge cases matter.
- Design a first-run experience for a meditation app aimed at skeptical beginners.
Research & Accessibility
What the interviewer is testing: how they validate with users and design for accessibility.
- How do you validate a design when you have no time and no research budget?
- How do you design for accessibility from the start, not as an afterthought?
Behavioral
What the interviewer is testing: handling critique, disagreement with a PM, and craft under deadline.
- Tell me about a time you shipped something the data later proved was wrong. What did you do?
- Describe a decision where you disagreed with your director and had to defend your call.
- Tell me about the hardest prioritization trade-off you personally owned.
