Hey,
How common is it for the admissions office to contact applicants letting them know to “expect an email or telephone call” from the alumni interviewer? It’s also odd that the interview they assigned me lives in a state in the northeast, while I’m from way south.
Sometimes there are areas with active alumni clubs but not interviewers. I do meetings for Cornell and where I used to live, near a big city, there were only 6 interviewers in my region even though there were hundreds of alumni.
