Hey there my friend,
Things look pretty good for starters, but I'll be honest it's a bit hard to evaluate without some more info (and of course the GMAT!!!). But let me share some initial thoughts with you.
So first of all the good stuff - bulge bracket bank is for sure fantastic, as is IIT (although your grades are a bit average). I don't yet have a clear idea what you do here, what responsibilities you have nor how fast you have moved. Also, it will make a big difference if you are front office or back office... Big in the sense that, if you get a 700+ you are for sure good for Top 30 schools. The question is more the bottom half or the top half?
Your challenges will be: Indian candidate, with a degree in tech, so far I haven't seen anything yet that makes your profile unique (even if it is very good.... and I'm not saying you don't have it!! You have to FIND it!), and so-so GPA. If you have some extra goodies stuck in your profile and can get a fantastic GMAT then that would be the best thing you could do for yourself.
One note about your goals... I like them. They are unique and interesting... buuuuuuut it doesn't yet make logical sense given your experience. How will you make them make sense?
Soooo, if you have any other questions, don't hesitate.
Otherwise good luck on your exam.
