Columbia Interview is done..Met with an alum at the University Club of New York..Amazing building..
I reached the club 10 min nefore my 6:30 PM interview. Got the chance to relax a bit.
The alum was a super nice guy. It was very conversational and lasted around 35 minutes. The interview format was general with resume based and personal interest based questions.
The interviewer did indicate that he liked my approach to the Why MBA part of it and was positive about my candidacy..I just hope the adcom thinks likewise :)

So that means 2 colleges are done from my end..Tuck and Columbia..Nothing to do but wait on these...

Till then the journey continues with my other target schools..Essays to write and Recos to collect :)
