Eight UI Designer interview questions, and what the interviewer is thinking

1. Why do you want to work as a UI designer, and what does your typical working week involve?

Why they ask: They want to see you understand the day-to-day craft and are genuinely motivated by it.

2. How do you use visual hierarchy, typography and spacing to guide a user's eye on a busy screen?

Why they ask: They are testing core visual design fundamentals, not just tool skills.

3. How do you make sure your interface designs meet WCAG 2.2 AA, particularly around colour contrast and focus states?

Why they ask: Accessibility compliance is a legal and ethical expectation in the UK, and they want practical knowledge.

4. How do you set up components, variants and auto layout in Figma so a design stays flexible and easy to maintain?

Why they ask: They want evidence of efficient, scalable Figma practice rather than static artwork.

5. How do you approach designing responsive layouts across mobile, tablet and desktop?

Why they ask: They are checking you can design for real devices and hand over something developers can build.

6. What does a good developer handover look like to you, and how do you check the finished build matches your design?

Why they ask: Handover quality is a common source of friction, so they want to know you close the loop.

7. A senior stakeholder insists on a design change that you believe will harm usability. What would you do?

Why they ask: They want to see how you advocate for users while managing senior relationships.

8. Tell me about a time you redesigned an interface and measurably improved how it performed.

Why they ask: They want proof your design work leads to outcomes, not just nicer visuals.

A sample answer to question 1

Why do you want to work as a UI designer, and what does your typical working week involve?

I'm drawn to UI design because it sits where visual craft meets problem solving. A typical week starts with understanding the brief and any research findings, then moving from low-fidelity wireframes to high-fidelity screens in Figma. I build components with auto layout and variables, check them against our design system, and prototype key flows so developers and stakeholders can react to something tangible. I spend a good part of the week in critique sessions, refining spacing, hierarchy and colour, and the rest handing over specs, answering developer questions and reviewing builds in staging to make sure the finished product matches the design. I also check contrast and focus states as I go rather than leaving accessibility until the end. What I enjoy most is seeing a clunky screen become something people use without thinking about it, and knowing small decisions, like button placement or label wording, change completion rates.

Common mistake to avoid: Describing it as just making things look nice; Ignoring handover and QA
