One of my friends told me that these three institutes must be in this order like; IIIT A>>> NIT Bhopal>= NIT Rourkela. Although he was a student of NIT Rourkela.

He stated that between these three, Rourkela and Bhopal are more or less equal. However, both of these institutes consist of some advantages and disadvantages as well. 

If NIT Bhopal is considered and compared with NIT Rourkela, then it must be said that NIT Bhopal's strength is a large batch size; IT+CSE. But the main advantage of NIT Bhopal is the location and nearby airport transport facilities that conceal all the advantages of this institute. For this reason, NIT Bhopal experiences big recruiters every year, and NIT Rourkela misses this entirely. This is the reason why NIT Bhopal is one step ahead of NIT Rourkela.

However, at NIT Rourkela, M.Tech in Computer Science and Engineering (CSE) is almost similar to doing M.Tech in IITs. But in the case of Bhopal, the students can sit for placements for all the big companies in the campus recruitment process along with B.Tech companies. It will be better to avoid IIIT Allahabad for doing M.Tech in CSE, as placement opportunities in this institute are not good. This thing is that IIIT Allahabad does not allow M.Tech students to attend for placement in the on-campus recruitment process.

Thus, it can be stated that for the B.Tech course, IIIT Allahabad>> NIT Bhopal> NIT Rourkela.
