Hello Shabeer, 

There are a couple of options for you which I will state below:

1. You can go for an MTech by appearing for exams like GATE, and other state exams. Through GATE you can even be called for an interview with top companies of the country like ONGC, GAIL, BHEL, etc. You even have a shot at MTech in an IIT, if you have a rank lesser than 600. If you're in the top 100 ranks, then you have a shot at MTech from IISC.

2. You can work as an airforce core engineer by appearing for AFCAT.

3. You can appear for ESE- engineering services exam through UPSC. People clearing this exam are the top technocrats of this country. 

4. Some states conduct state level exams to recruit trainee engineers for government.

5. PSUs like VIZAG steel,  ISRO, BAARC have their own exams and you can appear for them.
