The interviewer was over 45 minutes late for the interview, had others waiting. Did not apologize for tardiness. Then the late interviewer handed me off to a different interviewer who was already there, this 2nd interviewer was very stiff, did not look at my resume beforehand. I notified him that because of the interview starting late, I was slightly limited on time (because I was a student, I had to go to class). The late interviewer came back into the room a bit later, interrupting the interview and said he wanted to listen-in on the interview. He then proceeded to talk for a while, without interviewing me or asking questions.
