CGC Landran and CGC Jhanjeri are the same and run by the same management. The faculties of the college are also the same. The placements for both campuses take place at the same time. The students sit together for their placements.
I have a few friends at both institutes and most of them recommend Chandigarh Engineering college Landran campus over Jhanjeri campus because this campus is the oldest, the environment is good, and it is located near to Mohali.
CGC Landran is better in terms of infrastructure and faculty members as well. The CSC department of this college is good. According to the recent placement highlights the average and highest CTC offered at the institutes is 7 LPA and 35 LPA.
