I use a fizzbuzz-level question in my phonescreens for all levels of SDEs, and about 1/2 fail to solve it (from a wide range of experience, I've given up trying to predict who will fail).

The other 1/2 quickly solve it and we move on to better stuff.

Yeah, similar. If you're experienced enough, fizzbuzz is just so trivial enough that you can do it before the application. Hell, just tell them to copy paste the answer. Someone inadvertently pastes the wrong programming language for it too, which suggests they're either not reading the question or not comfortable with the language they're interviewing for.
