I was interviewed by the CEO, who was incredibly rude. He spoke to me as if I was dumb and kept using an impatient tone of voice. He also asked me who set up the interview, and no doubt went to yell at that nice person for making him waste his time. Ended the interview by saying he already had two people in the position anyway, so I'm not sure why I was called into the interview in the first place. The interview itself was not difficult, but it was clear that he did not even look at my resume or cover letter at all before the interview.
