Hi,
    See engineering is the most populated field in the present scenario . There is a lot of demand of every field in engineering whether it is rubber making to big train manufacturing everywhere engineering is required.  So most important branches are it, cse, mechanical and civil. All the best!

Each branches are good it depends on your interest & capability.  Some of the core branches:

CSE: It is not only development & coding  but also testing and life-time support, which needs CSE engineers in drove. The major chunk of jobs offered in India, every year, are for CS engineers.
