Should I prefer civil engineering in IIT Hyderabad or CSE in RVCE?

My suggestion would be to opt for IIT Hyderabad Civil Engineering and prepare for a branch change. 

IITs cannot be compared to any private college other than BITS. Even if you are unable to change your branch, don’t feel disheartened as the IIT Brand name is more than enough. 

I know many people who were part of the Chemical, Biotech, and Civil Engineering branches of IIT and are earning more than 12 LPA currently. Irrespective of the branch you belong to, IITs offer an excellent coding culture making you proficient in the same. The quality of peer groups you will be interacting with is also better at IITs than at private colleges like RVCE. 

All in all, IIT as a brand is better than RVCE and other private colleges except BITS.
