Fizzbuzz is an example, I've never seen it on its own. A company doing a pre-screen test would normally put 2-3 small tests, the easiest one fizzbuzz-like, for a total of 1-1.5h. Multiply that by the number of companies you are interviewing and that can easily be 8-15h in total. I'm glad I didn't have to do that.
