Interviewer was not very friendly, sounded like he wasn't interested in interviewing, and was fishing for cookie cutter answers to cookie cutter questions. One question involved a non-standard data structure that the interviewer refused to define for me but wanted to ask questions about. I was going off of general programming experience and college CS, but it seems like that isn't enough and you need to read all of those "100 CS interview secrets!" books cover to cover so you have the same question bank as them. If accepted, I wouldn't have joined, because the interview was indicative of a workplace where requirements are not properly defined and you're just supposed to dream up what is expected of you among uncooperative peers. I ended up interviewing for and accepting a level 3 position at a company of equal reputation a month after this.
