I would strongly oppose Fizzbuzz. Why?

It's so well known that everyone uses it to study for their interview. You'll end up hiring someone who just memorized the solution.

Instead, come up with your own unique programming challenge that the candidate hasn't seen before. It should be about as easy / hard as Fizzbuzz.

Related: I once interviewed a candidate who came across as knowing my questions ahead of time, and delivering a well-reheased answer. I made up a question on the spot, and got a "this wasn't supposed to be on the test" tone of voice in the answer. I rejected the candidate.

Technical interviews aren't things that the candidate should memorize and rehearse. That's why I'd never ask Fizzbuzz.

I don’t think anyone need to “memorize and rehearse” Fizzbuzz, the whole idea is it is so trivial that one can solve it on the spot without prior knowledge.

If one is concerned about people memorizing answer, it is pretty simple to change the question a bit to make it non-recognizeable,
