Hey y'all! Please be more specific about your "interview" offers.
There is a big difference between having a potential PI reach out to chat with you about your interest/previous experience versus being officially invited by the program coordinator to the formal interview day. Folks are noting that they've been invited to interview for programs that have not even had their department meetings to choose candidates for interview day, which is (unintentionally, I'm certain) misleading to others on this thread. We're all in this together, and not trying to up the anxiety measure any more than is already part and parcel of this process. Specificity and candor are key. Thanks, cheers, and good luck to all!
