The answer may seem a little bit biased, but everything written in the following is my friend's personal experience.
He was in the batch of 2018 in the CS Department. His JEE Main rank was 28 (AIR), and he selected this institute as there were no other options like IITs or top NITs.
It was completely unbelievable to him as the institute was recently established. Within just 2 years, it became so developed; however, everything happened due to NIT Jamshedpur's mentorship.
This institute did not have any discrimination; rather, you will get the opportunity to sit in the NIT Jamshedpur placement process. It is no doubt a great prospect for the students of this institute.
There was a break up for IIIT, and within the next 2 years, as my friend told me, it might become low.
Additionally, this institute's official strength is approximately 120-180, which considers the best for this new institute. It is also a great achievement for this institute.
