Just FYI, Penn has a pretty detailed web page regarding applicant interviews, which includes:
“Please don’t worry if you’re not invited to interview. Since we aren’t able to reach every applicant, not having an interview won’t be held against you in our review.”
“It’s our policy that applicants can’t request interviews.”
I am not suggesting that a request would create a problem. Make your own decision. But, I thought this information was helpful.
