Hello Ankit, hope you're doing good..

Well, both the colleges you mentioned are full of scope and job opportunities in the near future. So its upto your interest and convenience that which college you'll choose for your career. Well if you have interest in electrical engineering, then you may join IITG, but you may also go for Kharagpur because it has its own charm and prestige.

Hope this helps you out....

All the best!!
