Here's a couple of words of advice I typically share with Chicago candidates, but others might appreciate:

First, although this can be stressful, it should also be fun:  lots of law faculty will want to talk about you and your ideas over the next couple of days!   You will form intellectual and professional relationships even from interviews that don't lead to callbacks.  Enjoy the scholarly dialogue and learn from it.

Second, remember that every hiring committee is a black box:  you don't know its internal priorities and squabbles, its biases and agendas.  So don't waste time speculating about how you did (candidates, in my experience, are uneven judges of their performance, in both directions), and remember you are bound to bomb an interview, but life will go on.  Forget about it.

Third, bear in mind that hiring committees come to the hiring convention with different charges from their home schools.  Some will be authorized to offer some callbacks even before the weekend is out; others will have to report back to the rest of the committee at home before doing anything.  Don't draw inferences from silence, or from the fact that someone you know got a callback before the weekend was over–even when hiring committees are allowed to make some quick callback offers, it's almost always the case that the full hiring committee back home will make decisions about other callbacks at a later date.

Best of luck to all the job seekers out there!
