Hii Ranjan..

First of all congratulations for performing so well in JEE advance.

I would suggest you to go for IIT BHU CSE since it is a very prestigious college. When placements of both IIT BHU and IIT Hyderabad CSE is being compared then the placements at BHU is much better and the highest package at BHU is 2.5 crores till now.

Not only placements but college culture at IIT BHU is very good. Many good companies come for placement in CSE department at BHU and even the alumini network is very broad at IIT BHU.

My person suggestions for you would be to go for IIT BHU CSE rather than IIT Hyderabad CSE.

Hope it helps.

Best of luck for your future..
