Had my interview last week, and for those with forthcoming interviews, do not stress. I found the whole process to be very conversational. Just re-read your essays, know a few things that make you want to get and MBA and go to CBS, and have some stories about teams and ethics in mind.
For those that have interviewed, will I get an email from the adcom when my reviewer has submitted their feedback? If not, is there an update posted to the main application system or to the interview system? It looks like the turnaround time after interview can be as quick as one day, so I am hoping I hear back this week.
