Dear candidate NERIST is overall a renowned institution teaching Computer Science Engineering curriculum quite nicely. But since it's a very old Institute some of the facilities have declined in its qualities. But coming to North Eastern Hills University, it has developed a lot in recent years. Coming to sophisticated infrastructure, their huge book collection in the library, placements with average salary package of 3-5 LPA offered by IT companies like TCS, Cognizant, Wipro, Infosys and more companies are yet to come in future.
