Product Designer
Interview Questions

Twenty-four questions hiring teams actually ask product designers — with guidance on what a strong answer covers, and a worked example for each.

Interviewing for a product design role rarely tests recall — it tests judgment. These questions probe how you handle ambiguity, tradeoffs, feedback, and shipping under constraints, not just how well you can talk about your portfolio. Skim the section you're prepping for, or read start to finish.
