Design Ux interview prep.

Behavioural questions to expect

1. Walk me through your CV.
2. Tell me about your most impactful design project.
3. Tell me about a weakness, a failure, or feedback you've received and worked on.
4. Why consumer internet design — and why this vs enterprise SaaS or pure brand?
5. Which design area would you want to own, and why?
6. Why the firm?
7. How would you describe the firm's design organisation + product in your own words?
8. How does design actually create value at a consumer-internet firm?

Technical concepts to master

• Design process + the double diamond

  Discover + define (first diamond) · Develop + deliver (second diamond) · Prototyping + fidelity progression · Test + A/B + iterate

• Design system + tokens + brand fluency

  Tokens · Components + motion · Brand fluency within the system · Governance + contribution + adoption

• Consumer funnel + onboarding + engagement design

  Funnel + drop-off design · Onboarding + first-value design · Engagement + habit loops · Mobile-first + platform conventions

• Accessibility + inclusive design + mobile

  WCAG 2.1 / 2.2 AA · Screen reader + keyboard + assistive tech · Mobile accessibility — touch + gesture + reach · Inclusive design (beyond disability)

Practical drills

• Walk me through one of your strongest portfolio case studies — the user behavior + problem, the research, the process, the decisions, the A/B + outcome.
• [Interviewer presents a screen or describes a flow.] Critique this design.
• the firm wants to redesign mobile onboarding (or a key conversion flow). Walk me through your approach — the user journey, key screens, edge cases, and how you'd A/B-test.

Smart-question anchors

• Team + scope — design team shape, what the role would own in 6-12 months
• Design system + brand — current state, governance, contribution model, brand fluency
• Research + A/B partnership — researchers vs designer-led, A/B cadence, how data shapes decisions
• Accessibility + craft posture — firm's WCAG conformance, dedicated role, recent accessibility work
• Critique + design culture — critique cadence, design reviews, shipping decisions
