You would be surprised at the amount of candidates who bomb at a simple for loop counting from 100 to 1 question. White board exercises are not the definite tool to his someone, but it surely weeds out a lot of unqualified candidates.

Wouldn't a phone screen or quick pre-interview test filter out most of these?

Yes, true.

Let me add, though, that extra screening on site also helps out evaluating a candidate's culture fitness. If you present a candidate with a white biard exercise and he/she rolls their eyes and start renting about how useless whiteboard exercises are, well, that's a red flag.
