Hello aspirant. Right now , almost everything is having opportunities. Every single nook and corner of a branch has opportunities for development. I can tell you which is growing in recent years. In the field of technology and computer science, artificial intelligence using data analytics is the growing field, its growing so rapid that it is having wide range of opportunities now . To pursue that, computer science or IT are the few of the best branches.

Apart from that ece, eee is also growing in their own stream. So it's not possible to tell something is going to be constant

Hope this helps

Regards
