Dear aspirant, every field we choose of our own choice has future and is fruitful always. Every stream has jobs and if you have interest in that particular subject you have a great chance to grow in the same field as well.So if you have interest in the subject you should persue with mtech only and VIT Vellore is a very good institution for the study of engineering if you can apply fot it. You can also appear for the gate exam or get the knowledge of the institutions near your home or where you can go. Every institution is good, all the matters is your hardwork and confidence to get a good job.

Hope it helps

All the best:)
