Hello there , NIT Trichy last year placement percentage recorded in UG batch was 96.2%, and the highest share of placement occupied by CSE with 100% placed students. And average salary fluctuates between 8-10 Lpa depending on the number of recruits the high paying companies make. Highest salary package could be between 25-30 Lpa. But about this year  stats. be may be little different. And I will also add this point that when it comes ti CSE , where you study matters much less than the skills and knowledge you acquire. If you build a personal brand for yourself and go off campus, everything becomes immaterial.

Have a nice day
