Hello Suprabath,

NIT, Warangal is ranked higher than VNIT, Nagpur. NITW is ranked 4 in overall NIT ranking and VNIT is ranked number 5. Now, if we talk about the branches both branches are good but Biotechnology is a new branch in India so the job opportunities are a little lower for a graduate but you can go towards research side jobs. Whereas you can get a decent job from Chemical Engineering just after graduation. So now it's up to you what you want to choose.

All The Best.

According to me branch matters the most. So you can choose biotechnology as biotechnology is progressing at a good level. There are many scopes for higher studies and research also. You can go to other countries for research purposes. There are varieties of opportunities available
