My luck with interviews has got be one of the best, let me tell you.
I just got back from a prospective interview only to not actually have the interview, or do anything really. The reason for that was that the person I was supposed to meet with was out of the country. Yep. The guy was out of the country and no one else at the company knew about the meeting. So yeah. Fun times huh?
The only consolation is that we managed to reschedule the meeting rather quickly and it wasn't as weird as having the guy who tried to hire you move on to another job in an entirely different field the moment you go in for an interview. That definitely happened.
