I recently interviewed for 4 jobs, one of them was one of these type of "you must implement this in 1 hour". It was painful. I didn't finish in time. Apparently the idea was you much choose language X, it will e pretty easy with language X. I chose Y, and they said why did you choose Y, that was stupid. Result - I chose one of my other 3 offers, took the one that made me a staff programmer. And I live in Seattle, ha ha bay area.
