Hey!

According to the reviews, main campus of Vellore is most considered, however all the campuses have basic infrastructure facilities and good faculty members. But main campus has more area than other campuses  Also, if you are in chennai or any other campus then you need to travel to main campus every time a company visits and around every 2-3 days a company visits for placements of CSE.

Hope it helped to clear your delimma

Thank you
