@karstu - I spoke with someone in admissions about the Alumni Interview details and here is what I have for you:
If you have requested an interview and have yet to hear back, check your spam folder (especially if you are using Gmail).
If you are an ED applicant who requested an interview more than a couple weeks ago, and have yet to hear back, you should email your Tulane admission counselor.
If you are an EA applicant who requested an interview then you don’t need to do anything - they are still matching alumni with applicants.
