I am 2013 graduate from NIT Rourkela, B.Tech CSE.
Academic wise, don’t expect much from profs. (which is the case in almost all NITs excep top 3/4). You need to do a lot on your own.
Placement wise it’s very good. As mentioned by other people, almsot all big names come to pick CS students. And year by year, the number of companies, quality of companies and pkg they are offering are also going up in a significant manner. For 2013 batch, average pkg was approx 6+ with more than 40% of batch holding a pkg of 7+ and highest pkg was 10+. For 2015 batch though the exact figure of avg pkg I don’t know, highest was 15+.
Among all NITs it will rank around 5th or 6th for CSE. So after surathkal, trichy, warangle, allahabad, it can be placed. (bhopal, rourkela, durgapur will be almost equivalent). CSE from an old NIT will be definitely a big plus. If not in campus, you will get many opprtunities from bigger companies once you are in industry.
