UX Portfolio Guide: How to Write Case Studies That Get Interviews

Last updated on

A UX portfolio that gets interviews contains two or three case studies, each telling a clear story: the problem, your role, the research, the key insights, the design decisions (and why), testing and iteration, the outcome and what you learned. Hiring managers skim. Lead with the problem and outcome, show your reasoning, and keep each case study readable in about five minutes.

Key takeaways

  • Process and reasoning matter more than polished final screens.
  • Make your role explicit, especially on team projects.
  • Show iteration: the “before and after” based on testing.
  • Be honest about constraints and what you’d change.

What makes a case study stand out

  • A specific problem: “First-time users abandoned sign-up at the address step”, not “I redesigned an app”.
  • Real users: even five interviews beat assumptions.
  • Visible reasoning: annotate screens with why.
  • Iteration: show a version that failed testing and how you fixed it.
  • Accessibility considered: contrast, labels, keyboard use.

Project ideas for a junior portfolio

  1. Redesign a frustrating flow in a local service, such as a clinic booking or council form, testing with real users.
  2. A non-profit or small business project solving a real operational problem.
  3. An internal tool improvement at your current job (with permission).
  4. A mobile app concept for an underserved group you understand well because of your background.

Common portfolio mistakes

  • Only “Dribbble shots”, with no process
  • Walls of text with no visuals, or visuals with no explanation
  • Fake metrics or unclear claims (be honest; observed improvements are fine)
  • Hiding your role on group projects
  • Too many weak projects instead of two strong ones

Presenting your portfolio in interviews

Prepare a 10-minute walkthrough of your best case study: problem → insight → key decision → test result → outcome. Expect “Why did you choose that?” and “What would you change?”

Frequently asked questions

How many case studies should a UX portfolio have? +

Two or three detailed case studies are enough for a junior role. Quality and clarity of process matter far more than quantity.

Can I use course projects in my UX portfolio? +

Yes, especially early on, but make them your own: choose a real problem, talk to real users and show genuine iteration. Projects with real users or real organisations carry more weight.

Should my UX portfolio be a website or a PDF? +

A simple website is standard, built on a portfolio platform or a basic site, with a PDF version for applications that request one. Fast loading and easy reading matter more than fancy design.

What do hiring managers look for in a UX portfolio? +

Clear problem framing, evidence of research, sound reasoning for design decisions, testing and iteration, measurable or observed outcomes, and honest reflection on what you'd do differently.
