Firstly if you consider KJ Somaiya College, their placement records vary , in general the salary packages offered are between 2-4 LPA but in recent years there were companies offering 5LPA jobs. You will get enough guidance from your teachers regarding placements. Next considering Bennett University, here the placements are really good. The median salary package expected can be 5-6 LPA. Many companies are recruiting freshers of CSE batch every year. However PDEU would not be the best among the three because here you can expect salary packages of 2-4 LPA. Hope it helps,

Good luck !! Know more about them
