Interview at my old office this coming Monday, with an administrator that was one of my strongest contacts outside my actual group of supervisors. This person knows my work, knows what I'm capable of, and has seen me at my best (and also seen me drop the ball rather spectacularly once or twice...)

Interview is to replace a friend who's transferred to a different position.

Really, I can't imagine a better situation for an interview, short of actually being related to the person I'm interviewing with. Oh, I hope, I hope, I hope.
