Dont be nervous. Everyone is very welcoming, very accessible. We had a really good interview group, I thought everyone was really nice and easy to talk to. Nothing to worry about, they are just looking to know more about you, so talk about yourself, academics, ec's, life experiences, they want to know about it! It's a closed file interview, so they don't know what is in your application. Also, they give you the chance to ask about your file if you have any questions (ie, missing pre-req classes, etc). Good luck on the interview, lol just don't get stuck in the large "parking lot" that is Atlanta rush hour traffic, like what happened to me after the interview.
