B.Tech Scope

As is understandable from the name. Automobile is focused on Automobiles. But Mechanical Is a very diverse core brance. Everything you can see feel around you is mechanical in nature. Or requires concepts of mechanical engineering.
Thus i would advice as you to keep otions open and take Mechanical Enginnering from good colleges like BITS, Lovely Professional University, SRM etc. Once you get in final year you can choose specialization as Automobile engineering.

Dear gauarv ! this is an excellent university but there are better private universities that provide assured placement.some of these institutes are:
1.Lovely Professional University
2.Symbiosis
3.KIIT
i have heard that Lovely Professional University venture in their students unmatched entrepreneurial skills that makes their students easily employable.even this university provides an excellent platform to showcase your skils.
choose wisely.

it is not compulsory to do ms or mba after btech but if u'l do it den dat will make alot of difference. i would advice you to do either of them.
all the best

yes definitely you can do mba after doing btech

If your background is from Engineering. It's a plus point in MBA. If you have any work experience, you can do executive MBA also. It is beneficial in the end.
