NIT JALANDHAR CSE should be prioritized over NIT JAMSHEDPUR CSE and NIT PATNA CSE. If you look at their placement, you'll see that there isn't much of a difference between these colleges when it comes to this branch. All you need is good infrastructure and a welcoming atmosphere; otherwise, sooner or later you will find yourself regretting your choice somewhere on campus. When discussing the infrastructure of these colleges, you must consider their NIRF ranking.
To be honest, NIT Patna's campus and facilities are fairly mediocre and unsatisfactory. Then there's NIT Jamshedpur, which is right next door. It, too, needs to improve significantly. However, because it is located in an industrial area, it attracts a large number of students who study Electrical, Mechanical, and other related fields.
