I was put on the waitlist without interview in the Early Action Round. I was invited to interview along with Round 1 applicants.
However, I didn't get a status update email on R1 decision date. This confused me a lot as I stayed up all night hoping for either an accept or a reject. I even called the admissions office helpline for clarification, but they couldn't tell me anything.
After agonizing over the weekend, I went back and read all the emails and links that Fuqua had shared. Finally got to the relevant information:
"On the decision release date for each round, you will be informed if you are admitted, and if not, your status will remain waitlisted. As such, please be sure to keep us informed of any changes in your contact information."
So seems like Fuqua doesn't deny anyone directly from the waitlist.
