Tiring and cold people for no reason. One of the interviewers was pretty judgmental about my career path, while the other seemed enthusiastic but more direct than an average interview process. They asked me to answer to an analytical question and then almost yelled at me for not getting it right ?!? The interviewer closed the interview saying they would contact me next week with the next steps, as their feedback was positive. Never heard back from them, not even a rejection e-mail.
