I was emailed today about my contact for my alumni interview, has anyone gone through one of these yet? (I am applying as a transfer)
I did - very nerve wracking.
I did one, but I am a freshman application. It was a very good experience. My interviewer was easygoing and genuinely wanted to know more about me. I wouldnt recommend being scared of it. This is a time for you to tell them how awesome you are
It was really nice experiencing. My interviewer was so nice and genuinely wanted to know more about me like the person above said. He even took me to breakfast by house. So I would say dont be nervous, its a time to truly show who you are 
I loved my interviewer. We spoke for around 30 minutes, she was incredibly friendly. I told her at the beginning that I was nervous, but that broke the ice a bit. Don’t put too much thought into your answers (like in terms of memorizing word for word) but do take time to anticipate the normal interview questions they will ask and get a good grasp on what your truthful honest answer is. I think towards to even of the interview, I felt great!
