I don't see the distinction. For example, I code...but to get my code out I have to deal with like 4 other teams and their ridiculousness...

If I were at a smaller shop, I'd have to be better at dealing with my coworkers and maybe the customers.

As dumb as some of the interview process is, it does indeed weed out people who won't be good in that environment.

(With that said, I've been in completely adversarial interviews that had nothing to do with the work in question and was just an opportunity for the principle to shit on his lessers).
