I've had 2 interviews; 1 in person and 1 phone interview, and there are pros and cons to both. The great thing about the phone interview is you can have your notes right there in front of you without needing to worry about looking at them too much and maintining eye contact with your interviewers. The bad thing is it can be a little awkward at first over the phone since you can't see the interviewer(s) and may not know when to speak. Likewise, the interviewer may not know when you are finished with your answer so there can be some awkward pauses.
I was asked a variety of questions in both my interviews:
1. Describe a challenge you've had to overcome.
2. Name 3 attributes that would make a grad student successful in this program.
3. Tell us about something in the field that has peaked your interest and why.
4. What books have you read recently?
5. Why this profession? Why this specific program?
Make sure your answers are in-line with what was written in your SOP and application. Also, have several questions prepared for the interviewers that will show your interest in the program. You don't have to ask them all since they may answer some in your conversation beforehand, but it is good to be prepared. Just make sure they are thoughtful and show you've done your research. The question portion was the best part of my phone interview. It gave the faculty a chance to speak about their area of knowledge and 'sell" the program. You can really tell how much enthusiasm they have for the profession during this time and the what type of mentor they would be.
Most of all, just be yourself. I received some great advice before my phone interview and I'm glad I took it. I also really wanted the spot and was told to let that come through and to not downplay my interest for fear of coming off as "too excited." They want people that are passionate and determined. Last thing- make sure to send thank you emails (and follow up questions if you have them) to everyone you speak with.
Good luck!
