Hey there IndianExpress!
So sorry to hear you didn't get the results you wanted, but you are still young and have plenty of opportunity to evaluate what might have gone wrong and reapply
Let's start maybe with your school list, which is fine, but maybe a wee bit too ambitious (or lacking a safe school). I think even as a non-Indian with the same profile, top schools like Duke and Booth don't take that many Big four folks (unless you are really the best of the best in the big 4). It's a little bit of a common profile. I think the other schools on your list are schools at which you would be more competitive.
But other than that, everything seems to be int he right place - you have the right alma mater, you have a good GMAT a long career in a good place etc. I can't really tell you what might have gone wrong without having a look at your application, but I would guess one of two things 1. Not unique enough - Although you have great stuff, it is possible that you made an application that didn't make you stand out enough. This is especially important given the huge and difficult pool you come from 2. Not making the most of your essays - this is the most common area where people fail. It could be, as you mentioned related to your goals, it could be other things too.
My advice to you would be to send over your application for a Ding review, and I'll set one of my consultants to work with you and figure out what went wrong as well as come up with a strategy for the future.
