Hello Manoj, See Engineering subject has importance and scope in their respective field, the only thing is what we want. In the current scenario, there are 10 field that has importance in the various sector for Engineering candidate - Software engineering, Aerospace engineering, Civil engineering, Biomedical Engineering, and Environmental Engineering, Petroleum Engineering, Project Development engineering, Chemical engineering and mechanical engineering, Future friendly engineering (such as Nano tech., Biometrics, Cloud computing and Artificial Intelligence).

So, you need to find which Field you have interest in, which field you always have had eagar for know more about, In Which field you can Make your future career...

All has wide range of placement... Specially Petroleum, chemical, Future friendly, and aerospace and even Mechanical in defence sector... Best of luck... 

Every Branch is in demand dear and has its Scope, it is your limited thinking which outdates the other branches and thinks for selecting shortcuts for getting job oriented branch. Think beyond, you'll know that engineering is much more than you can think of. It's in evolution and will always be. Just be practical and ask your conscience what you are good at and passionate about. The answers for the branch will come within as you have all of them embedded in yourself.
