I've recently been advising a student who is trying to gain admission to philosophy grad school. One of the programs to which he has applied has invited him for a campus visit, one component of which will be an interview with the department's faculty.
I must admit I was a bit taken aback when he told me about the interview, since it does not seem to be a common practice for grad school admissions (at least in philosophy — I'm not sure about the norms in other disciplines). With that in mind, I was hoping readers might have advice or insight about these interviews.
If you were interviewed as part of the graduate school admissions process, what kinds of questions were you asked and how might a student best prepare for such an interview?
If you've been on 'the other side' and have conducted such interviews, what are faculty hoping to learn from them and what would you recommend students do to prepare for them?
