I'm currently applying for lecturing jobs at a couple of universities (in the US), and one of these is a place that had accepted me in its Ph.D. program a few years back, an offer which I ended up turning down to go somewhere else (this was done in a very courteous way and I do not believe I left a bad impression).

1. Do you think my history with the school could have an adverse effect on my current application?
2. If not, is there any reason to mention somehow that I applied to their graduate program (I'm worried that if I avoid the "elephant in the room" they might become suspicious)?
