Product Designer interview questions

A product design interview is a conversation about decisions, not screens. Expect to explain why a design is the way it is, what research told you, and how you reacted when engineers or data pushed back.

Questions to expect

  1. Walk me through a project you are proud of.

    What they listen for

    The problem and the people before the pixels. Then the options you threw away and why.

  2. Tell me about a time research changed your mind.

    What they listen for

    What you believed, what you saw users do, and what you redrew because of it.

  3. How do you handle feedback you disagree with?

    What they listen for

    That you look for the problem behind the comment, and that you can defend a choice without being defensive.

  4. Describe a design that could not be built as you wanted.

    What they listen for

    How you worked with engineering to keep what mattered and let go of the rest.

  5. How do you know a design worked?

    What they listen for

    A measure or an observation after release, not the team's applause at the review.

One answer, before and after

Tell me about a time research changed your mind.

You said

We did user testing on the new onboarding and got lots of feedback, some good and some less good. Users had some trouble in places, so we iterated on the design several times and the final version was much cleaner.

Try

I was sure our five-step onboarding was too long and designed a single screen. In testing, six of eight people froze on it: too many choices at once. I went back to steps, but showed progress and cut two questions. Completion went from 54 % to 71 %.

What you believed, what you saw, what you changed, and the result.
