Our mentors meet with so many talented product designers who have great portfolios but still struggle with their onsite interviews. Sometimes, people let their nerves get the best of them, so we also wanted to provide some tips to keep in mind while you’re in the interview.

Start with clarifying questions

Sometimes, interviewers make a question intentionally vague. You don’t need to jump in right away. Always take about 15-30 seconds to think about clarifying questions, like “Can I wireframe this out first?” or “How in-depth do you want the design?”

Proactively show a positive signal

As you work, give background information on what you are doing. This is strong tactic candidates use to reduce opportunities for negative language or information. The tradeoff is time, but in general, 30-second “tidbits” of knowledge usually help.

Give context

Context statements show the recruiter that you know the reasoning behind why you are doing something rather than just doing them. How you are interpreted will change based on the context that you give.

Know how to get help

More often than not, the interviewer will be ok helping you out, but sometimes, they just hate the word “hint.” So, a better approach would be to say, “my assumptions are X and Y, and I’m thinking of doing Z. But I’m struggling with solving [problem].” You can also ask collaborative questions like,

  • Do you have any thoughts?
  • Do you think I’m going down the right direction?
  • Are my assumptions incorrect?

With these questions & tips in your back pocket, you should be more than prepared for your next technical onsite product design interview.  And if you are looking to advance your skills, check out the how to find remote design jobs to land the best interviews for your career.
