Hello Pavitran Raj,
You got a good question in your mind,I will help you to get the right answer what should you do after completing ECE course in Btech.
First of all you should believe you are an engineer,other than this you should make one vision to reach your goal,
Generally Electronics and communications Engineering give you a path in designing,developing and testing the electronic equipment i.e used in the various systems,also in manufacturing of communications and broadcast systems.By these you have to choose your own path in which aspect you are fit or having a personal interest to work on it.
The very surprise thing is over 70 percent of industry are using electronics such many manufactures of household and much more.
Hope you Understand
