Interview tips for this role
- Review the candidate's portfolio before the interview and ask about specific design decisions. The best UX designers can explain the reasoning behind every choice.
- Include a whiteboard or design exercise. Ask candidates to sketch a solution to a realistic problem. Process matters more than polish here.
- Test their research skills by asking how they would approach a specific research question relevant to your product.
- Pay attention to how they talk about users. Great UX designers reference real user behaviours and quotes, not assumptions about what users want.
- Assess their ability to work with constraints. The best UX designers produce excellent work within technical, business and time limitations.
Frequently asked questions
Should UX designers know how to code?
Basic HTML and CSS knowledge helps UX designers understand implementation constraints and communicate more effectively with developers. However, deep coding skills are not necessary. Prioritise design thinking, research skills and prototyping ability over coding proficiency.
How do you evaluate a UX design portfolio?
Look for clear articulation of the design process, not just polished final screens. Strong portfolios show the problem definition, research findings, iteration and measurable outcomes. Be cautious of portfolios that only show visual design without evidence of user research or strategic thinking.
What is the difference between UX and UI design?
UX design focuses on the overall experience, including research, information architecture, interaction patterns and usability. UI design focuses on the visual layer, including typography, colour, spacing and visual hierarchy. Many designers do both, but they are distinct skill sets.
