I like this a lot. Works well for both parties. Pro tip for candidates: after you solve the problem, when you share it with the team this is a good time to show how friendly and open you are. "Gosh guys, I've never been much good at TDD, but I limited the code to less than 50 lines, so I thought for such a small project I could squeak by" or "What a fun project! Yeah, that screen design sucks. I suck at UI design. From a technical angle, though, it was fun and I enjoyed playing with the problem" People want to know both how confident/competent you are and how you handle weakness. If you're an ace on the technology, can talk a good game, and enjoy having people help improve your work? You're a keeper.
