Interview Help!!

[av2010]

I am an applicant for PhD Communication programs, and interviews aren't all that common.  I had specifically asked some of my colleagues who have PhDs and they said that I probably shouldn't expect interviews.  However, one school has emailed to schedule a phone interview, and I have no idea what kinds of questions they are going to ask and that I should prepare for.  My statement of purpose was very detailed in the research I want to work on, faculty whom I'd like to work with and why, my background, reasons for pursuing, etc.  I was very thorough in covering all the bases in my SOP.  I also had thorough conversations with graduate directors and faculty members at each school I applied.

Just wondering, what kinds of questions will be asked so that I can mentally prepare?!
