It was pretty informal at the time. However, the people there when I got hired are no longer there. We haven't been huge on excessively technical questions. I think they're stupid anyway. No one works that way. You've got Google and Stack Overflow to look up trivia. I can tell by just talking to someone for an hour if they have any clue or not. I don't care what specific programming language someone knows. That is actually barely relevant to the real problems of software development.
