I interviewed with a start-up mid-acquisition by Indeed and they paid me for my take-home project. Quality move but the rest of their behaviour was utterly reprehensible. I was mad/upset at the time but I'm now grateful.

Also, I had the time available to spend ~8-10 hours on a take-home project (paid or otherwise); most of the time the best candidates already have jobs and will rightfully tell you to pound sand.
