A professor at one of my schools (a top-10 program in the field) reached out to me to schedule an interview about 10 days ago. I responded with some times that would work for me, but didn't get a reply. After all of those times had passed, I sent another email listing my availability for the following week. Still no reply.
This interview seems to be part of the official process at the school, so I'm relatively confident that I won't be accepted without interviewing. Should I annoy this professor some more (or reach out to admissions), or just give up at this point?
