BTW, I heard an anecdote that during interviews at Microsoft, the interviewers sometimes "staged" a ferocious argument in order to test how the candidate reacted to extreme pressure and conflict. :)

I've heard this about Amazon too. I really, really despise this idea. This isn't the SEALs or Delta Force, you're going into an interview stressed as hell, worried about how you're going to perform technically and then some dick gets in your face trying to piss you off? I'm probably not going to react very well to that, and it's going to throw me off for the rest of the interview.
