National Institute of Technology, Tiruchirappalli and     

National Institute of Technology, Warangal are the best NIT college for CSE.

Since you asked for the best NIT college so I've discussed about National Institute of Technology, Trichy below :

Placements: Placements are very good here. In fact, this year there has been 100% placement for the students of Computer Science and Engineering. Overall, you will get placed with a very good package if you have talent, and if you don't have any talent, then also you will get placed but with a less package.

Infrastructure: Infrastructure of the college you can say good. It is a huge campus of 880 acres, which is the biggest NIT campus in India. The hostel rooms are decent. The library is brilliant. 24/7 Wi-Fi access is available. Sports facilities are also very good. There is a hospital and also a swimming pool.

Hope this helps. You can contact for any further guidelines.
