Hello Deepak, I would suggest you go to NIT Jaipur because it is one of the top 10 NITs in India. Although the placement in metallurgical won't be as better as the main branches like ECE and CSE the quality of professors there is very good. NIT Jaipur is older than NIT Jalandhar, so it is much more famous than NIT Jalandhar which will help during the placement.
