Hi, First thing there are job opportunities in this field but where will you lack then? they require mostly experienced candidates. Companies like Reliance, Nicol, Spic produce raw material and develop new products. So you will have to keep patience at first and it shall take time to get settlement.
second thing, if you do not want to continue with it you can plan to do Btech then.
You can think over all again and let me know if any problem. Good Luck.
