Most job opportunities for which btech stream?

Dear Meghma
There is no concept of the best jobs from a particular stream. The only thing is the course you opt and the knowledge you have at the end of the course. If you can present it and good at concept then there is always an opportunity waiting for you it might be in campus or even if you try from outside it is totally dependent on your knowledge and presentation skills.
So any stream with good related knowledge can get you a good job offer.
All the best.
