Technical Questions

Q

Tell us about one UX project from discovery to delivery. What evidence did you use to decide each step?

Strategy

Assesses end-to-end UX thinking, data literacy, and decision-making under ambiguity.

Q

How do you build and govern a scalable design system for product teams?

Strategy

Checks whether you can structure tokens/components, document decisions, and enable consistent delivery.

Behavioural Questions (STAR)

Q

A PM says your design is “too risky” and wants to revert to the old approach. How do you respond?

Strategy

Assesses collaboration, influence without ego, and the ability to de-risk with user evidence.

Q

How do you ensure accessibility across UX—especially for keyboard, screen readers, and motion sensitivities?

Strategy

Evaluates practical accessibility knowledge and how you integrate it into the workflow.

How recruiters evaluate your UX judgement (beyond “pretty screens”)

Recruiters look for a coherent narrative: you should be able to explain your assumptions, the evidence you collected, and how that evidence changed your design. A strong answer ties decisions to user outcomes using metrics such as task success rate, time-on-task, and error rate—rather than only visual preferences. Be ready to reference tooling you used in the process, such as Figma for prototyping, FigJam for workshops, and analytics platforms like GA4 or Amplitude to justify priorities. You should also show collaboration habits—e.g., how you aligned with PMs and engineers during discovery and how you supported implementation with specs and acceptance criteria in Jira. Finally, prepare 2–3 portfolio case studies with clear before/after outcomes and at least one moment where you iterated based on user feedback.

Live or take-home design exercises often appear in UK-style UX interviews because they reveal your thinking under time constraints. You might be asked to redesign a journey using a template (problem statement, assumptions, hypotheses, and test plan), or to produce a clickable prototype in Figma that includes key states and edge cases. Expect evaluators to probe how you balance discovery time versus delivery time, and whether you can defend your prioritisation using an approach like impact/effort or RICE. Some panels use a short whiteboard session (often ~30 minutes) to see your structure, while others give a take-home brief where you create screens plus a usability test plan within a fixed window (e.g., 24–48 hours). Either way, you’ll score higher if you clearly describe what you would measure after launch—such as conversion rate, activation metrics, or support ticket reduction—and how you would monitor risk.

Design system & component thinking: tokens, variants, and adoption metrics

When recruiters ask about design systems, they want to see whether you can create a system that teams can actually use—not just a set of components. Discuss how you structure tokens (colour, spacing, typography, and semantic names) so designers and developers share the same rules. Mention accessibility as a system requirement, such as maintaining WCAG AA contrast targets and ensuring focus states and error states are consistent across components. You should also cover component anatomy: base component, variants (size, state, theme), and interaction behaviour, documented with guidance and examples. Tools they may expect you to use include Figma libraries, component sets, and documentation practices like a mini “spec” or living guidelines page. A high-quality answer includes governance and adoption outcomes too—how you handle requests, review changes, and track usage metrics such as component adoption rate or reduced redesign rework.

To make your answer more concrete, tie your approach to outcomes and workflow improvements. For example, you can explain how standardising forms and validation patterns reduced implementation variability and improved UX consistency. Share metrics like “40% reduction in design time per feature” or “fewer QA regression issues after release,” and explain how you measured them (e.g., Jira cycle time, QA defect counts, or user-reported issues). Recruiters also like to hear about edge cases: loading states, empty states, and error messaging, because these determine whether a system works in real conditions. If you’ve worked with cross-platform constraints, mention collaboration with engineering and how you align on component behaviour for web and mobile. Finally, highlight how you enable others: workshops, office hours, and examples that make it easy for non-designers to select the correct pattern rather than inventing new ones.

Turning disagreements into user evidence (PM partnership under pressure)

In UX interviews, collaboration questions often test your posture when stakeholders disagree with your design. The best responses start with listening: clarify the underlying concern, whether it’s feasibility, timeline, compliance, or business priority, not just “risk” as a vague label. Then translate the debate into user evidence by referencing what you know from research, usability testing, and analytics. Tools you can name include Hotjar for session recordings, user interview templates for consistent synthesis, and usability scripts for moderated sessions. When you propose next steps, suggest low-cost ways to de-risk quickly—such as rapid usability testing, expert review, or an A/B test with defined success metrics. Show you understand that decision-making should be testable: specify what outcome would change your mind, such as conversion lift, task success, or reduced error rate.

A compelling example includes both how you communicate and how you iterate. For instance, you can propose a comparison: “We’ll keep the core UX model but adjust hierarchy and microcopy,” then validate with a small study before investing in full implementation. Recruiters want to hear that you don’t “win by persuasion”; you win by aligning the team on measurable user outcomes. Mention how you would present trade-offs clearly—time vs impact, complexity vs learnability—and how you would document decisions for engineering handoff. In practice, this could mean adding annotations in Figma, agreeing on acceptance criteria in Jira, and ensuring the prototype represents the interaction model accurately. You’ll stand out if you describe how you supported implementation after the decision—e.g., by preparing edge-case designs, error state flows, and usability notes so the delivered experience matches the tested one.

Accessibility as a lived design practice (not a final checklist)

Accessibility questions are increasingly technical because employers need designers who can bake inclusive design into workflows. Your answer should mention concrete standards and checks, such as WCAG 2.1 AA requirements for colour contrast and keyboard accessibility. Explain how you design for focus order, visible focus indicators, and accessible names for form fields so screen readers announce information correctly. If you’ve used tools like Figma accessibility plugins, Stark, or contrast checkers, name them and describe how they influenced decisions early. Then show how you test: prototypes validated with VoiceOver (iOS) or NVDA (Windows), plus checks for readable error messages and recovery paths. Strong candidates also address motion and cognitive accessibility—e.g., ensuring important feedback is not only indicated by animation and providing clear, consistent layouts that reduce cognitive load.

To demonstrate maturity, link accessibility to UX outcomes. For example, explain how improving labels and error handling can reduce user drop-off and support volume, and how clearer hierarchy can improve comprehension across audiences. You can mention measurable KPIs such as reduced form completion errors, improved accessibility-related usability task success, or improvements in NPS/CSAT from users who rely on assistive technologies. Describe how you collaborate with stakeholders: product and engineering on semantic markup expectations, content designers on plain language and error wording, and QA teams on test plans. If applicable, reference certifications or training you’ve completed, such as IAAP or formal accessibility training, but keep it grounded in what you actually do. Finally, show that you iterate: accessibility findings from usability tests should feed directly into component updates and guidance within your design system.
