      Product Designer Interview

      29 Dec 2025
      Anonymous interview candidate
      London, England
      No offer
      Positive experience
      Difficult interview

      Application

      I applied online. The process took 3 weeks. I interviewed at Perk (London, England) in Jan 2025

      Interview

      Passed 3 stages, unfortunately dropped at the whiteboard challenge (still sad about this). Reflecting after thought that I got too fixated on showcasing some collaborative processes (to be fair that was listed as an expectation) and spend too much time trying to do a role play with 2 other designers to show how I'd work in a team. In the end they game me a very logical and structured task which could be doable if I did what I'd normally do: figure out what the product does, who uses it and how + what were technical constraints.

      Interview questions [1]

      Question 1

      I had a real product task to solve but based on another product (not their), so you can call it hypothetical. There was some fake data for me for a start and I had a goal to move certain metrics with my changes.
