Hey everyone, the interview today went really well. I was pretty nervous, but it wasn't super intimidating (its my first interview so I don't have anything to compare it to!). The order of events went something like this:
-Arrive and wait in the cafeteria (my advice, just start talking to the other people-- it helped me relax). There were A LOT of people there -- close to thirty!
-We broke off into groups of five or six (your nametag will have a colored dot on it to denote your group) for the tours, which were fairly short.
-There is a short break before the interview. Take advantage of it and use the restroom and eat a granola bar. My stomach was growling near the end of the interview -- hope no one heard it!
-The tour ended at the interview rooms. My group consisted of two guys, three girls. They asked a question and went around with each person answering, but they alternated who got to answer first.
-The questions were very straightforward (don't be afraid to ask them repeat it if you are the fourth person to answer, cause sometimes people go on tangents in their answers. You want to make sure you answer the actual prompt!)
-My interviewers were very nice (there were two of them) and they didn't harass any of our answers.
Overall, try not to be nervous (if you can), be friendly and smile. At the end of the interview, I made sure to thank the interviewers and shake hands with them (I was the only one in my group to do this). These guys will be on the adcom the following day, so try to make a positive lasting impression!
Good luck!!! Let me know how it goes!
EDIT: Also at the end they will ask you if you have any questions for them. I would recommend having one or two meaningful questions to show that you have really looked into their program!
