I am an international student. I got an interview invite on 12th and did it last week.
Just wanted to share some insights as I have received quite a few from the members on this website

.
They asked the typical questions: why an MBA, why Cornell, why now, what are your career goals, etc. After all the hours spent on the essays and on self reflection, answering those questions should be pretty straight forward.
It is a blind interview, so the interviewer does not get to read the essays, and only has the CV. In addition, he has a few pointers from the school about the aspects on which he should focus. For me, it was mostly to test the weakest aspect of my application, and check if and how you have improved on it.
Now waiting for the final decision, quite scary!
Good luck to all!
