I'm going to be interviewing at UMich for the Biomedical Engineering PhD program, which is one of my top choices, so I'm pretty excited! However, I just got my tentative itinerary for my trip, and I noticed that of the 8 half-hour slots allotted for one-on-one interviews with PIs, only four of mine are filled. Granted, I only listed 6 professors of interest when I was asked, but I also wasn't sure of how many I should have sent in at the time.
Should I be concerned that I'm given so much free time? I know that I'll probably appreciate the breaks to gather myself between interviews, but I'm worried that more competitive students may have all slots filled and have to go back-to-back with interviews. Should I be worried about my situation, or am I overthinking it?
Thanks!
