Frequently Asked Questions

Should I include a design exercise in the interview?

Yes, but keep it short (15-20 min) and realistic. Avoid complete redesigns. Prefer a specific problem: improve a flow, redesign a screen or propose a solution to identified user pain point.

How to evaluate a junior UX Designer without portfolio?

Request a case study beforehand (2-3h max). Evaluate approach, not just result. A junior showing good methodology, curiosity and learning ability has more potential than a senior who only does pixel-pushing.

UX Designer, UI Designer or Product Designer: what's the difference?

UX Designer focuses on research and information architecture. UI Designer works on visual interface. Product Designer combines both and participates in product strategy. 2026 trend is full-stack Product Designer.

What UX metrics to ask about?

Ask what metrics they track: task completion rate, SUS (System Usability Scale), NPS, completion time, error rate. A good UX Designer measures work impact and can cite quantified improvements.

How to evaluate accessibility sensitivity?

Ask about WCAG, accessibility audit tools (axe, Lighthouse), and concrete decisions made to improve accessibility. A candidate who's never thought about a11y in 2026 is behind market practices.
