NIT Silchar is a prestigious engineering college that imparts quality education in various fields. However, the PG courses aren't very well-known and only the UG courses have gained fame over time. It is therefore advisable to check the profiles of the teachers in the respective department.

Additionally, NIT Silchar is located in a remote location and you might find it difficult to procure your equipment for projects. MTech depends on the quality of the research and project you have completed and if you fail to accomplish it your MTech degree is invaluable. 

Most companies visiting NIT Silchar prefer BTech students to MTech students. So getting a good job let alone a core job is very difficult here. The institute has no international ties so your future prospects may narrow down further.

Consider all the above factors before making your final decision!
