well, that answer isn't going to help any. I don't speak with any authority at all, but I have heard of it happening to people I know who interviewed, and the few I know were hired. I guess they might have a couple things they want to look at a bit more or discuss. And I would say you are a civilian type, as the military people are such a hot commodity that they get the word instantly, so don't feel bad.
The people I know had their pilot friends write a quick e mail to Chip Long or Kimball Stone, reiterating that the person was a good candidate. Either way, they were hired. I think a quick e mail to those same people from you, thanking them for the opportunity to interview, as well as your strong desire to work at AA wouldn't hurt.
Good luck, and hope you get it. Let us know.
As an aside, who told you that you were going to the review?
