There is actually a question I really want to ask, but I'm not sure how to word it/when to ask/whom to ask.
I am EXTREMELY interested in the POI at a university I applied to and I have an interview there in a few weeks; however, from the very beginning I have always received responses from his graduate students rather than my POI himself. This worries me about how he will be to have as a mentor. How would I refer to this in the interview? Obviously, I feel I will more likely direct this question to his current graduate students, but I don't want to come off as rude. Perhaps he is an excellent mentor, but just receives too many outside E-mails to respond to them all. When asked if I have any questions, should I simply ask him how his mentorship works exactly? Should I talk to the current graduate students and explain exactly what I'm thinking and see what they say? I just don't want me asking this question to be taken in a negative light. I think it shows I care!
