Take a deep breath and don't worry about it. Be yourself. Be honest. The best answers can be the most simple and obvious ones. I would say that being invited for an interview is 80% of the battle. I just started at Georgetown so the interview process is very fresh in my mind. The faculty and staff interviewers are all very approachable and easy-going. There is nothing intimidating - everything is very meant to be conversational. And I don't know what other people might be leading you to believe, but they do not push the scholarship in anyway. I would say that half my class is doing it and the other half isn't. If you have any questions, I'm happy to discuss more privately.
