The single most important point is that the process is candidate unfriendly. You can get away with being candidate unfriendly during college hiring. Maybe. If you're not hiring at a top CS school. You can't get away with it when you are trying to reel in a 10x superstar. Those types of candidates need to be wooed. If you make someone do too much work in the process, you'll only wind up with candidates who hate their jobs, not love their jobs. That's not to say don't make sure people are smart. And the idea of proving coding skills is good too. But the manner has to be consistent with respecting the time and skills of an expert.
