Here are a few things to think about while waiting for that phone call inviting you to interview for a faculty position. First, you may have been thinking about/comparing all the places you applied to, since you have been reading a bit about each place and probably talking to your significant other (if you have one) about what life would be like in some of these places. DO NOT turn any invitations for interviews down on the basis of these thoughts and discussions (really the only reason to turn down an interview is if you have already accepted a position elsewhere). I have witnessed postdocs declining a request to interview for reasons of geography or spousal happiness.
And you may say, drdrA- why should I interview in a place I think I don’t really want to go to? Well, I say honestly that it’s difficult to get a really accurate idea of a place on paper. Best to visit the department, put faces/personalities/projects to the names on the list of potential colleagues, see the campus and the town, and gather the kinds of information you can’t get without visiting in person to make those kinds of decisions. Second, I’ve said it before and I’m going to say it again- you get a job by having an offer (preferably more than one), and you get an offer by having interviews… and the more the better.
When you get the call inviting you for an interview- it will usually be from either the search committee chair or the department chair. Be interested in the position; ask a few questions about the department that leap out from your preparation- find out the usual format/schedule for interviews in the department. Will you be giving one talk, a formal seminar on your research, or two- the formal seminar and a more informal chalk talk… You may be asked to give some thought to potential colleagues that you might like to meet with, and the dates of your visit will probably be decided during this phone call and subsequent contact by phone or email.
Once this business is settled, an administrative person will usually contact you to arrange your travel. I know I shouldn’t have to say this but be kind to administrative staff- they are doing their best to arrange schedules for multiple candidates (4-5 is a pretty predictable pool to interview) to visit with numerous faculty with busy schedules. You are an invited guest, don’t forget that.
