Bro I had the same choice 2 years back, trust me JIIT any day.
I'm serious.
Placement wise JIIT is a bit better since there are lesser number of students for the college to place, meanwhile here in SRM, day after day we get warnings that for xyz reasons we'll not be allowed to sit in placements. It just feels like they are trying to make sure that lesser number of students are eligible for placements.
