Frequently Asked Questions about Product Designer Interviews
How many projects should be in a product design portfolio?
3–5 deep case studies are more effective than 10 shallow showcases. Each case should show your thinking process, research methods, iteration, and measurable outcomes — not just beautiful screens.
What is a design challenge in an interview?
You're given a design problem (sometimes with a time limit) and asked to work through it: define the user, identify problems, sketch solutions, and critique your own work. Companies test your thinking process, not your visual execution speed.
Do product designers need to know how to code?
Not required, but front-end knowledge (HTML/CSS basics) helps you understand what's feasible and collaborate better with engineers. Familiarity with design tokens and component libraries is increasingly expected.
