I actually don't think I've had anyone completely blow up on it, except once a long time ago in a previous company with someone who turned out couldn't even do helloworld. They usually do it and later all the devs look at the solution if they like it or not. In my company you can't know how everyone votes. It's just a bunch of anonymous "+1"s or "-1" and after the votes are added up if the candidate got a huge negative number it's a no-go. Around zero is handled case-by-case I think and huge positive is extend offer. A neutral person does the vote-counting. I guess the phone screens are doing a pretty good job of dropping anyone who'd bomb it in the office.
So... actually, I don't know if it's filtering anything really. It's just interesting to watch people do it and it at least establishes that the candidate isn't a complete faker.
