Interview Questions for a UI Designer
Interview a UI designer by examining how they craft polished, on-brand interfaces grounded in typography, color, layout, and a scalable design system. Assess advanced Figma skill, responsive design, accessibility-aware visual decisions, interaction states and motion, and clean developer handoff. Strong candidates show a portfolio with rationale behind visual choices and faithful, shipped implementations.
Last updated
Run this interview through the candidate's portfolio, asking why behind each decision rather than just admiring the visuals. The best UI designers think in systems and constraints — reusable components, contrast and focus states, responsive behavior, and handoff that engineers can implement faithfully. Probe how they balance brand polish with accessibility and how they collaborate with UX and engineering.
Technical & Role-Specific
What to look for: A clear visual hierarchy rationale, type scale and contrast reasoning, intentional spacing, and decisions tied to brand and usability rather than taste alone.
What to look for: Component variants and properties, design tokens, naming conventions, documentation of when to use what, and how it stays maintainable as the product grows.
What to look for: Knowledge of WCAG contrast ratios, visible focus indicators, not relying on color alone, and checking accessibility during design rather than after.
What to look for: Breakpoint strategy, fluid versus fixed elements, content prioritization on small screens, and designing for real constraints rather than only desktop comps.
What to look for: Documenting default, hover, active, disabled, error, and loading states, motion timing and easing, and purposeful micro-interactions that aid usability.
What to look for: Organized components, tokens, specs, redlines or auto-layout, edge cases, and partnering with engineers rather than throwing files over the wall.
Behavioral & Past Experience
What to look for: A real contribution, governance and adoption challenges, and measurable consistency or velocity gains for the team.
What to look for: Partnering with engineers, prioritizing which fidelity battles matter, and using a system or QA process to keep implementation faithful.
What to look for: Openness to critique, separating ego from the work, and iterating toward a stronger outcome.
What to look for: A concrete trade-off, refusing to sacrifice accessibility for aesthetics, and a creative solution that satisfied both.
Situational & Problem-Solving
What to look for: Educating on contrast standards, offering compliant alternatives that keep the aesthetic, and holding the accessibility line.
What to look for: Deciding between a one-off and a new system component, documenting it, and avoiding fragmentation or duplicate components.
What to look for: Collaborating with UX, proposing layout adjustments, and solving for small-screen behavior without losing the intent of the flow.
What to look for: Understanding the constraint, prioritizing the interactions that matter most, and proposing a simpler version that preserves the purpose.
Collaboration & Culture
What to look for: Respecting the UX intent, early alignment, and a shared language about hierarchy and interaction rather than reskinning in isolation.
What to look for: Proactive specs, being available for questions, design QA against builds, and treating handoff as a conversation not a deliverable.
What to look for: Shared system, usage rules, design reviews, and tokens that enforce consistency across contributors.
What to look for: Framing feedback against goals and principles, separating preference from problems, and staying open to critique of their own visuals without defensiveness.
UI Designer interview scorecard
Score every candidate on the same criteria, immediately after the interview, using evidence you actually heard rather than an overall impression. Agree the criteria with the panel before the first interview — deciding what counts after you have met people is how the loudest interviewer wins the debrief.

|---|---|---|
| Technical & Role-Specific | What the candidate actually said or did, in their own example — not your impression of it | 1 2 3 4 5 |
| Behavioral & Past Experience | What the candidate actually said or did, in their own example — not your impression of it | 1 2 3 4 5 |
| Situational & Problem-Solving | What the candidate actually said or did, in their own example — not your impression of it | 1 2 3 4 5 |
| Collaboration & Culture | What the candidate actually said or did, in their own example — not your impression of it | 1 2 3 4 5 |
| Overall recommendation | Strong no / no / mixed / yes / strong yes, with the single reason that decided it | - |

Questions to avoid asking a UI Designer
Exactly which questions are unlawful depends on where you are hiring, and the rules change — so treat this as the list of topics to route through your own employment counsel, not as a legal standard. The practical test that holds everywhere: if the answer could not change how the person does this job, you have no reason to ask it.
