Hii,do not worry i am here to help you according to your query.Let me start about thier placement and infrastructure.
Placements : The placements for M.Tech. Is quite poor. The percentage of people placed from both the batch of 2018 and 2017 was quite small. In the batch of 2018, the only notable company for placement for the M.Tech in Mechanical Engineering were the PIAGGIO. There were no R&D companies for the M.Tech students and the M.Tech students weren't allowed to sit on the placement for the PSUs.
Infrastructure : The infrastructure in NIT silchar is average for a technical institute. The hostels and classrooms are quite adequate and built sufficiently advanced to satisfy the needs of the students and teachers alike. However, the library facility is not upto the mark.
Hope,this information helpful for you.
