I applied for the full-time program and was under the impression that an interview was not required as it is not listed under the application checklist page on Carey's website. In any case, 11pm sounds odd, are you outside of the U.S by chance? I'm sure an interview is a positive sign though and it'll be a good chance to show off even more of yourself to the adcoms.
If you haven't guessed, I haven't received any word from the admissions team. This rubs me the wrong way as their website states approximately 2-3 weeks to reach a decision (its been about 6-7 weeks for me now).
I'm actually in state. She replied yesterday confirming the time again so I guess that's the actual time. Do you have any experience with interviews? Is this the only school you've applied to?
I didn't request one, but I am happy. I would assume if I was flat out rejected I wouldn't have been contacted. I wouldn't be put off by my experience as I'm going for my MS. It may be different for the full MBA program.
