What should I include in my UX design portfolio for interviews?
Include 3-5 case studies that demonstrate your end-to-end design process: problem definition, user research, ideation, wireframing, prototyping, usability testing, and final designs with measurable outcomes. Show your thinking process and decision rationale, not just polished final screens. Include both shipped products and concept work if you are early in your career.
How long should a UX portfolio presentation be?
Aim for 30-45 minutes covering 2-3 case studies, leaving time for questions. Each case study should take 10-15 minutes. Focus on storytelling: the problem, your process, key decisions and trade-offs, and measurable results. Practice your timing and be prepared to go deeper on any project if the interviewer asks follow-up questions.
Do UX designers need to code?
Coding is not required but is increasingly valuable. Understanding HTML, CSS, and basic JavaScript helps you design feasible solutions, communicate effectively with developers, and prototype interactions. Some companies value design-engineering hybrids. At minimum, understand responsive design principles, platform-specific patterns, and technical constraints that affect design decisions.
What UX tools should I know for interviews?
Figma is the industry standard for UI design and prototyping. Also know tools for user research (Maze, UserTesting, Dovetail), design systems (Figma with auto-layout and variants), and collaboration (FigJam, Miro). Experience with motion design (After Effects, Principle) and data visualization is a bonus. Focus on demonstrating your thinking process rather than tool proficiency.
How are UX design interviews different from UI design interviews?
UX interviews emphasize research methods, information architecture, interaction design, and measuring usability. UI interviews focus more on visual design skills, typography, color theory, and brand expression. In practice, many roles combine both. Portfolio reviews for UX roles weight process and user research insights, while UI-focused roles prioritize visual polish and design craft.
