Master Figma deeply — components, auto layout, variants and prototyping are tested in most live design challenges.
Know design-system thinking: tokens, spacing scales, type ramps and reusable components, not just one-off screens.
Brush up on accessibility (contrast, focus states, WCAG) and responsive design — strong signals for senior UI roles.
Practice taking critique gracefully: interviewers test how you respond to feedback, so engage with it rather than defend.
