Ive had a lot of interviews. one was like that, first interview went perfectly, but the second was with a idiot that just wanted his lunch. I didnt blame him as he had just driven for 4 hours for my interview... but that said Im glad I didnt get it as the job was the most basic it support job you could get - working with the most stupid people for a type of company that is imo quite evil.... and I have a much better job now.
