Hey,
I just completed my interview with Karan Gupta and the interview was great. It lasted for around 30-35 minutes and I was asked questions about my work, reasons for IE, etc. I have even applied to INSEAD and NYU and I think the admission process for all these schools is pretty much the same. In fact, from all my interviews, the IE interview was the best. I am quite keen on IE and hope I get in. I have spoke to some current students and they have said great things about the school.
My fingers are crossed.
