One of my friends studied environmental engineering at NIT Trichy. According to him, he is quite satisfied with this college placement. He further mentions that this college provides the best placement for the students of M.Tech compared to other IIT colleges. 

He claimed that NIT Trichy is better than all the newer IITs and other NITs. This college is even better than IIT Roorkee in terms of M.Tech placement opportunities. 

Obviously, the placement stats differ every year but the percentage of the students from the M.tech branch is around 63.2% this year. It is quite good considering the pandemic situation.
