Electronics and Communication Engineering

If your college is good enough to provide you a better placement, then don't look for another course, because one year or two year experience is far better than your new course. If you don't get placed, then I will suggest that you must do M.Tech in VLSI domain, or whatever you want. I said M.Tech because moving from technical field to non-technical is easy, but you have worked for 4 years on same thing then why will you go for MBA or other courses. Don't be a path follower always be a path creator. So, choose whatever you want. Or else
For your career it will be better to do B.Tech or do apprentices in any government organization and to improve skills and command on ECE application you join ESTC MSME training center. There are different courses in these centers.
