A&M was super organized. They put a lot of time, effort, and staff resources into the interview day, and both of my interviewers had thoroughly reviewed my file. My interview was mostly conversational, and I didn't have any hardball questions. The questions were very specific to my personal experiences and not generic.
There was breakfast and lunch (provided by the Army recruiter), and a charter bus took us to tour the gross anatomy lab and St. Joseph, which is beautiful. Definitely bring flats to change into. There is a lot of walking, and almost all the girls brought comfy shoes for the tours. It was a very long interview day, but they gave us a lot of information, and I walked away feeling like I knew what the school was all about.
Hope this helps! It was fun!
