I once applied for a large school HS HBD gig. Even though 4 of the 5 members of the interview panel were from the music department, NONE of the questions I was asked in the 30 minute interview were specific to the position. You would think that they would at least want to know about my philosophy and approach to running a band program or classroom management....nope. The most probing question I got was, "Did you have any trouble finding the school".
Another instance happened right out of college. I flew down from the Midwest to interview for an assistant MS gig. Again, no questions regarding the job. One question I was asked was what the best way to eat corn-on-the-cob was (no, seriously, I was asked that). You might think they asked that as an "icebreaker" at the beginning to help the candidate relax...but this came right in the middle of the interview...and the person asking had looked down at a piece of paper as if they actually had that question written down.
Another poster mentioned making sure your references are good (which is an excellent suggestion), but a school isn't going to call you for an interview if your references are bad.
I'm sorry, but if a school isn't interested enough in me to ask relevant and direct questions regarding how I would run the program and why, and instead are going to waste my time with condescending questions that have no relevance because they already know who they want, I would rather they not contact me at all.
