Gather 11 of your finest department members (oh wait! that's the whole department), put on your best frown, and sit around a table grilling the interviewee until he's making stupid jokes to lighten the mood. Then bring in the Supervisors--three of them--who all think they have an interest in what happens in your department despite the fact that they got lost on the way there. The Supervisors will ask a number of unrelated and stupid questions that have no bearing on the job just to confuse the interview and test his frustration level.
