I am happy to extend you to the invitation to participate in annual programming contest of IIIT Hyderabad. It's an ACM style programming contest, except that it's for individuals and not teams.
You will have a chance to devour some really nice(hopefully!) problems. I think considering the wide difficulty levels in problems everyone will find some interesting/challenging problems to solve.
It begins on 25th Jan, 2015 at 1400 IST.
