Hey,
The overall experience was really good. The people at Fuqua really take care of you and make you feel welcome, right from the tour to the lecture to lunch. You will always have someone talk to you.
Also, the interview is really relaxed. I had a second year student talk to me, the interview was about 40-45 minutes and we covered a lot of material. There is no pressure, the interviewer is very friendly, and questions are very typical. You will be asked the usual What is your story, Why MBA, Why Duke, What are ST/LT goals, What are top 3 traits you look for in a leader, What is your leadership style, etc.
