The admissions coordinator went out of her way to tell us how friendly all the interviewers are. Then went on to say how they are not allowed to give any form of non-verbal communication (smiling, nodding, laughing, hand gestures etc. Stone faced robots are not friendly at all. Interview questions needed some specific knowledge.
What did you wish you had known ahead of time?
The complete lack of humanity that any of my interviewers demonstrated and the degree to which they expected answers on specific topics (medical marijuana, some pharmaceutical knowledge).
