The really horrifying thing about FizzBuzz is that it actually has useful power as a screening tool. No, I don't know how the hell these people accumulated years on their CV while being literally unable to even approximately code a FizzBuzz. But they're out there.
(I suspect Joel Spolsky's theory that it's the same 100 terrible guys applying for all the jobs.)
It's the same for sysadmins, by the way. We just went through a hiring round for a good Windows sysadmin. (Us Unix guys could all do Windows to pointy-click level, but needed someone who knew its evil little ways when something went subtly wrong.) Holy crap, you would not believe how many clearly useless bastards have literally twenty years as a Windows admin on their CV. We got someone who's great (and picked up the Linux side in short order), but it was slightly trepidatious.
