AIG interview questions

Six rounds with various people - 1 phone interview; 2 video interviews and 3 in-person. Each were very pleasant, courteous and respectful. I left each one with a good feeling except the final one which my interviewer was 4 minutes late, had not prepared and it ended 6 minutes early. (a 30 minute interview was really 20 minutes) When an interviewer is not prepared and seemingly does not want to do the interview it's very obvious and unpleasant.
