Interview - by college/school/degree?

I was wondering - are the alumni who interview us graduates of the same college/school that we are applying to? For example, if I’m applying to Wharton, my interviewer will be a Wharton grad? Wondering because a friend of mine who applied to Huntsman was interviewed by a Huntsman grad.

The interview coordinator will try to pair you with an interviewer in the same program, school etc. It is not a guarantee (depending on the availability).

my interviewer completed the same program that i applied.

They try but it’s not guaranteed. The bigger priority is getting as many people an interview as possible. I never interviewed anyone who was in the same field of study as me.
