Some students were thoroughly frazzled, but this could easily be attributable to the lateness of the interview (4:30...the D3's and D4's had been at it for 8 solid hours by that point)
What did you wish you had known ahead of time?
That the interview would be such a dynamic event. I spent as much time dialoguing with the D4 on the panel as the faculty and alumnus spent in traditional interview Q&A.
