Some of my friends attend NIT Trichy and based on the conversation I had with them, I can give you some idea about the placements at the institute. 

NIT Trichy opens the placement of software companies for the MCA students. Even the most renowned companies like Epic, Facebook, and Microsoft give placement to the students of the MCA course. The highest package that was offered to the students of the NIT Trichy from the MCA course is around 64 Lakhs per annum. 

According to the recent placement highlights, the average CTC offered by the institute is 6 LPA. Going by the past placement highlights is safe to say you will have good placement offers for an MCA from NIT Trichy.
