I got invited to on campus interviews after applying online. They were really disorganized. The signs on the first floor of the building where interviews were being held weren't clear about which room I was supposed to go to. I asked a receptionist and she told me to go to the 2nd floor. It turned out that wasn't the right floor so someone came looking for me after the time my interview was supposed to begin to direct me to the interview room on the 4th floor. The interviewer was very cold and seemed shocked that I didn't attend any info sessions or interview prep workshops they had held on campus. He asked me some very specific behavioral questions and one question on market sizing. He was not engaging at all. There was another person in the interview room who didn't say anything and just took notes. I guess they were just trying to test how I'd react to a bitter client....
