It was okay. Met with one person every hour. They all just read my resume and asked me to talk about it. There was one dude for the technical review that was relentless. Just answering the question and giving some insight on it wasn't enough. He kept asking me details of why I felt that way, apply it to a few scenarios, explain other ways to do it, which way is the best way, etc.. .etc... Not warm or nice, but I'm sure he has been burned by several employees in the past, so he was trying to be very thorough. Although, being thorough, and not liking the answers given doesn't give you the right to be condescending and short. Surprisingly, thoroughness through firing question after question at a candidate doesn't make them the most comfortable, and answering questions on the fly like that can be hard, and not always evident of a skillset, due to other factors. Something, I'm sure he didn't take into consideration. The rest of the group in the interview loop was pleasant.
