So I actually had a take home challenge for an interview a few months ago, which didn't ask for any code at all. Instead they gave us a prompt for something to build (a tool that could break down an image into it's component colours), and we basically built whatever we wanted.

Honestly one of the most fun interviews I've ever done - it involved really understanding the problem, and building an interesting solution. AI was totally allowed and expected, but you had to prove you understood the problem and what you'd made in the interview. I felt it was actually way better than traditional interviews, because it gave a chance to show the actual quality and thought of my work rather than a glorified logic puzzle.
