Hello Sunita!

IIIT Agartala is very recent, i.e. it was established in 2018. So, the first batch is yet to be graduated in 2022. So, it will hard to talk about the placements in this college. All of the faculty members are highly competent and benevolent. They are well experienced in their respective fields and have proper industrial knowledge. Overally, as per the student reviews the campus life in this college is pretty good. Numerous top-notch facilities like bank , library, dispensary, sports complex,canteen and WIFI are given by the institute. The college is situated in a place full of greenery. The mentor institute is NIT Agatala itself, so this IIT is not struggling in the competitive market. The total fees for B.Tech CSE program is about 9 lakhs in total(a little costlier than Pondicherry Engineering College). The cutoff of JEE Main also goes high for this college.

Pondicherry Engineering College was established in 1984 and has a good reputation in the foeld of engineering. Pondicherry engineering college is owned Govt of Puducherry a Central government institution.the college is recently approved by technological university of PEC by central government fully funded MHRD. The total course fees is about Rs 5.46 lakh. The infrastructure of this college is also developed with all necessary facilities.  The training and placement cell of the college facilitates campus recruitment process. Counselling and Career Guidance Centre (CCGC) is functioning in the college to provide career guidance and personal counseling to the students. The average package is about Rs.3.53-4LPA in the CSE dept.

The CSE dept. is well established in PEC, in my opinion, you must consider joining the institute if you are getting it. You must not miss the chance to join IIT Agartala also as it is an institute of national importance and will see much development in the coming years.
