Doing well on the fizzbuzz problems was not very correlated.
I think you're mis-using fizbuzz. You cannot really 'do well' on it. You can basically pass it or fail it. Failing means you're probably no good, but passing it doesn't prove anything.
That's the same thing though. If it's the same level of difficulty as fizzbuzz, it serves the same purpose: you can fail at it, but you can't really do well at it. All you can do is not fail.
