I agree. I’ve been doing alumni interviews for last 12 years or so at an Ivy and I would not do this. We don’t get the student’s academic or EC information. We only have what the student shares in our conversation. It’s the AOs job to assess their credentials, not ours. Our role is to get to know the student beyond the application and share that with admissions.
I’ve had several kids spin me a bull$%#t story (all from the same school, btw). I just let them talk. A little subsequent Socratic method gives me what I need. I then recount that story and the answers (or lack thereof) in my report. That’s all we can do. The AOs will use it as they see fit. And they don’t always get it right.
