Now none of my references has been contacted by any institution yet. Does that mean no one is interested in me, at least not yet? Do they usually make the short list after they get all the references' letters? Thanks!
In my experience, references are contacted at one of three points:
1. Before the short list is made.
2. After the short list is made, before the interviews begin.
3. After the interviews and before the offer is made.
In other words, there is no rule about when references are contacted. (Actually, there is a fourth window: when someone on the SC sees that one of your references is an old pal and calls her/him as soon as his/her name comes up.) There's no way to tell. So follow t_r_b's advice and try to work on something else.
Okay, so next question: How do you get the spouse to stop searching for places to live as soon as the application goes out? ;D
Some spouses need to do this, and stuff like this, in order to manage their anxiety. Some need to avoid it diligently so that they don't get their hopes up and have them dashed, over and over. Mine went through both phases, and a few others besides (our house has never been so clean). I think the goal should be to help the spouse understand what the spouse needs and give the spouse space to meet those needs.
