Hello Ajith,
I would say that in engineering each and every Field has good scope and all you need is experience and skills in that respective field. It is true that Computer Science has huge number of Jobs but most of them are either startups or not much recognized companies where you can't get MNC's kind of working environment. But yes if you have skills in CS then you can easily get into a good company. Similar thing is for other branches also. Core Branches have more government jobs than for CSE. So at the end it depends on you and your interest for a particular branch. Therefore choose wisely.
All the best !
