The initial meeting with the Dean is reduced to make room for the mock discussion. It is very similar to previous years aside from the time aspect. The 2 interviewers had my AMCAS.
Try to be relaxed, confident, and most of all enthusiastic! You will do great. My advice is to read through your AMCAS and secondary the night before. I also found that making one or two bullet points ("talking points") per each activity was really helpful for me. During the interview I then had talking points to reference that I could apply to questions I had not prepared for or previously thought about. For example, the interviewer may ask, "what has been your greatest failure." I would wait 2-4 seconds, reply first by restating question (which gave me more time), and then recall an applicable idea/talking point from my activities. It ended up being a great response. 🙂
It is also my first choice and cannot wait until I hear!
