Breaking into IB from a non-finance UG and finance major from Top15 MBA

Nobody can predict your future. They say. But its good to know the direction.
I did my undergrad in IT from a state ranked college in India and am currently pursuing an MBA in finance from a Top 15 ranked MBA college in the country. I couldn't get into a finance internship and as a result am doing my operations from a $1.1 b conglomerate family business in India.
I am yet to sit for my full-time interviews but they would start in right earnest from Sep onwards. I would like to work in IBD of a BB firm. I might even decide to work for 2-3 years in a private bank in investment management in India and then decide to apply for a M7MBA to get onto wall Street.
Would sincerely like to invite opinions from you guys regarding the career path.
