As a regular decision applicant I was contacted by a graduate of Stanford and asked if I wanted to participate in an interview. The next day, I replied yes and asked for possible times. After a week of no response, I sent a follow up email and waiting another full week with no further response. It’s now been 2 weeks since the first email I sent and I’m not sure what to do. I wasn’t given any other contact info and I’ve been constantly checking my spam and trash folders and there is nothing there.
I know as an alumni interviewer for a different university my university knows how to reach the interviewer if something goes wrong like this. It is even possible the person has an emergency of their own now since alum are doing it as a service to the school. Send a note over to your admissions rep to explaining what has happened and see if it can be straightened out.
My daughter recently completed her Stanford alum interview. Each interviewer may do it differently, but I know that in her case the initial email asking if she wanted an interview also had a link to a calendar of available times she could sign up for.
You might look at your first email and make sure it did not have a similar link you could use to respond, just in case your direct reply emails are going to spam or not being received.
Good luck.
I used to do alumni interviews for Duke. I always left a phone number along with my email address for students to contact me.
But 2 weeks is a long time with no contact. Sometimes the alumni association will have a regional alumni who is in charge. You could also try them.
