Probably the most unprofessional series of interviews I had so far in my career. First interview was cancelled a few hours before on the day of due to a scheduling conflict (good thing I often check my emails). Second attempt, I arrived on time only to be told to come back in two hors due to yet another scheduling conflict. When I finally met with the HR representative, the interviewer was insulting stating that the company was looking for a "mature" worker, "not some 20 something year old" to help support the team and back-up support the senior executive. (Let's put it this way: if it was not for a tight job market, I would have completely blown off the follow-up interview.) Second interviewer was at least pleasant and on time.
