Dear applicant it's great that you chose Electronics and Communication Engineering, now coming to NIT Trichy it has good infrastructure, placements offering 7-10 LPA packages. NIT Warangal is also a very good one however the placements are better in NIT Warangal. And the last one Surathkal is offering placements better than NIT Trichy but the faculties are better in NIT Trichy. The placements offered by NIT Surathkal are those jobs with 8-12 LPA packages. So there are different aspects I mentioned, hope it helps. And all the NITs have great infrastructure.

Good luck!!
