I'm not sure failing FizzBuzz means you lied on your CV. I suspect that many programmers go straight into an environment where they never have to think about algorithmic problems (even algorithms as simple as FizzBuzz), because others have already developed the platform and all the low-level fiddly bits (like containers, string types and functions, etc.), and they just spend their days plugging them together (query this API, update this database table, call this method on the view class).

I have interviewed candidates like this (not web, embedded systems) who talked a lot about the in-house frameworks of their previous employers, and could sketch how they would solve a problem in that environment in hand-waving terms, but couldn't implement strlen() (which would be much closer to the kind of coding they would have to do in our environment).
