AI skills test for product designers, on a real flow.

A good designer with AI starts from the evidence, keeps the rules that cannot move, and can explain every choice. The AI suggests; they decide.

Who the product designer AI skills test is for

  • Product designers
  • Mobile product designers

People who design flows in a live software product, with product managers and engineers. They start from research, data and support tickets, work within rules that cannot change, and hand over screens engineering can build.

An example AI skills task for product designers

One of our design tasks. Your dashboard has the rest, and you can bring your own.

The brief

Redesign an ID check

40% of new users drop off at the ID check when they sign up. Redesign that step so more of them get through. The ID check itself stays: the law requires it.

Then do the same for the address step, where 25% drop off.

  • TimeYou set it: a deadline, a time limit, or both. We recommend a deadline and no time limit, so they work the way they would in the job.

Questions about testing product designers’ AI skills

Can designers use Figma?

Yes. They can design in Figma as they normally would. We read their conversation with the AI tool and the screens they hand in.

Do you judge visual polish?

Yes, as part of the job. Sign off asks whether the screens are ready to hand to engineering, and your team judges the design itself when they watch the session.

Can we use a flow from our own product?

Yes. Bring your own task and we set it up with you.
