Which is best: NIT Calicut, NIT Bhopal, NIT Jaipur, or NIT Rourkela?

Honestly, it totally depends on your choice. If you want as per placement rankings then NIT Calicut surely beats NIT Rourkela which in turn is better than NIT Jaipur and NIT Bhopal. As some of my friends studied at NIT Rourkela, I can assure you that the overall campus is improving very fast. Also they offer good placements.

• Many famous companies are hiring a lot of students now. 
• If you are seeking a good infrastructure, NIT Rourkela is the best of all NITs. 
• For overall rankings, you can refer to MHRD, National Institute Ranking Framework (NIRF). 
• Certain departments at NITR leave a lot to be desired, where Calicut has the edge. 
• All is better than Bhopal and Jaipur in placements though. However, in terms of infrastructure, campus life, hostel life, sports facilities, the overall holistic development of an individual NIT Rourkela is a good option. 

Placements cannot be the only judging factor. Remember that students from the best departments at all these campuses do land up getting good IT jobs with a decent salary package.
