Yeah, it's very conversational... I wouldn't worry about the interview. BU was my first interview, and I was so nervous at my interview that when my interviewer asked if I had any questions, I blanked and told her I forgot them... then I remembered then I said I forgot again. Eventually I remembered, but I totally thought I bombed that interview :/. I did end up getting in though lol.
My interviewer just went through my app with me and asked me things like, so you're from xxx, and your parents are xxx, and things like that. The one question that threw me though, was she asked, why wouldn't UMDNJ want you? I really didn't know what to say... Funny thing is, UMDNJ waitlisted me, so obviously they didn't want me that bad... We also just talked about my braces, I have braces.
