Which college should I prefer for B.Tech CSE SRM Ramapuram campus or Chandigarh University?

I can give you the placements statistics of SRM. Rest, you can take the decision. http://www.srmuniv.ac.in/engineering/department-of-computer-science-engineering/placements.

I am very keen to help you. It's your decision, but yes, I advise you to compare both the institution and then go for the beat option. As far as I know, CU provides the best and the most desirable placements and internships among all other colleges in North India. All the best.

Of course, CSE in SRM over Chandigarh. SRM has a good placement ratio than Chandigarh University. No doubt in that. All the best.
