Hi manish,
That depends on the individual  actually and I would suggest you to do Mtech from NIT or IIT or MS in US or prepare well for jobs apply for them and work for the company
See manish Nowadays Btech turning out  into basic degree and students are unable to grab knowledge in their academics and working for a company with low salary,  this is the case for 70 students out of 100 students so the thing is go for MS/MTECH and learn more things related to your course deeply and get a job with high salary
Inbox me if you have any queries.

Hello manesh kumar
The best solution for this is after b tech if you go for job which is most passionate for you then you will gain for sure but if you are joined simply means you can face alot of difficulties but where as if your really interested in higher education then this option is good so my suggestion i have proposed
So now you should take the decision based on your passion
All the best
