Speaking candidly, there is probably something flat about your overall application. Whatever is in your essays/resume/recs wasn't enough to get interview invites, which from Kellogg is especially telling because they interview almost everyone (~90% of all applicants).
Find and
sell a spark. What makes you different from every other Indian/IT/720 applicant? Where do you really shine as an individual? What's your passion and how do you want to change the world? You need something to show the reviewer that you would be awesome at the school.
And manisjce is right, you've got a very narrow pool of schools. Which slightly troubles me, because if you really invested your time into research, I think you would have come to this same conclusion yourself. Lack of research might be another indicator of, what I suspect, is a flat application.
This doesn't mean you're not a fantastic leader or future business leader, but maybe your application didn't sell yourself well. Like manisjce, feel free to PM me and maybe I can eyeball some of your essays and stuff.
