Good ones aren't as common as they should be...bad interviews in general are disturbingly common, though, I don't think tech interviews in general or whiteboard specifically are any different.

Brainteasers and fizzbuzz are very different things though: I'm not totally against brain teasers as a prompt for discussion, but they're not my favorite types of questions, and can be hard to judge or of little use if the person either already knows the trick, or just doesn't figure it out. Fizzbuzz on the other hand makes a lot of sense when you're interviewing someone who you don't have any other knowledge of their coding. That type of question absolutely makes a good first pass filter: the problem is easy to explain, the implementation is trivial to do in a few minutes if you are at all qualified. Sure, it's annoying for an experienced person to have to do a fizzbuzz variant for the 200th time, but given that it takes almost no time, and helps the interviewer quickly jump to more advanced stuff or cut off an interview that isn't going to go anywhere, it's a pretty minor inconvenience.
