Interview Questions for a UX Designer

Walk me through one project in your portfolio from problem to outcome. Why did you make the key decisions you made?

What to look for: A clear problem definition, the reasoning behind decisions, evidence they considered alternatives, and honest reflection on what they'd change.

How do you decide what to research and which method to use before designing?

What to look for: Matching method to question (interviews for why, usability tests for can-they, analytics for what), and not over- or under-researching.

Show me a design you had to significantly change after testing. What did users do that surprised you?

What to look for: Genuine willingness to be wrong, learning from observed behavior, and translating a finding into a concrete design change.

Critique this screen of ours out loud. What works, what doesn't, and what would you test first?

What to look for: Structured critique tied to user goals and heuristics, specific not vague feedback, and prioritizing the highest-impact issue.

How do you design for accessibility, and where do you usually see teams cut corners?

What to look for: Beyond color contrast: keyboard nav, focus order, semantic structure, screen readers, and treating accessibility as baseline not polish.

When the data and your design intuition disagree, how do you resolve it?

What to look for: Respect for evidence, interrogating whether the metric measures the right thing, and a bias toward testing rather than ego or pure HiPPO.

How do you work with a design system: when do you follow it, and when do you break it?

What to look for: Valuing consistency and speed, but recognizing when a pattern fails the user and how to propose a system change rather than a one-off.

How do you measure whether a design actually succeeded after it shipped?

What to look for: Defining success up front, behavioral metrics tied to the user goal, and closing the loop with post-launch research.

Tell me about a time engineering said your design wasn't feasible. What happened next?

What to look for: Collaboration over insistence, finding the constraint early, and reaching a solution that still served the user.

Describe a time a stakeholder pushed a design choice you disagreed with. How did you handle it?

What to look for: Advocating with evidence and user empathy, knowing when to concede, and keeping the relationship intact.

Tell me about the most useful piece of critique you've ever received and what you did with it.

What to look for: Openness to feedback, separating self from the work, and a real behavior change as a result.

You're asked to redesign our onboarding but have no budget for research. How do you proceed responsibly?

What to look for: Scrappy research (support tickets, analytics, guerrilla tests), stating assumptions explicitly, and de-risking before launch.

A new feature must ship in two weeks. How do you scope the UX so it's good enough without cutting the wrong corners?

What to look for: Identifying the core user task, protecting critical-path usability, and being explicit about what's deferred.

Users say they want a feature, but you suspect it won't solve their real problem. What do you do?

What to look for: Digging past the stated want to the underlying job-to-be-done, and validating before building the literal request.
