Both NIT Warangal CSE and IIT Madras Civil are excellent academic institutions for students.
It’s a bit difficult to draw comparisons between NIT Warangal CSE program and CivIl Engineering program at IIT Madras, as they are different programs offered at different institutions. Both NIT Warangal and IIT Madras are highly respected institutions in their respective fields, and both offer excellent educational opportunities.
It’s a brainer that CSE is a much more preferred branch than civil engineering. But before choosing any branch you need to first determine your inclinations whether you want to go for IES, PWD job, a government sector job, or want to enter the corporate world. For most of these prospects, Civil is a better choice but for the corporate sector, CSE is better. Moreover,
I am not saying Civil has no opportunities, it’s just that CSE is the perfect choice for someone interested in programming and wants to enter the corporate sector.
Ultimately, the decision of which program is "better" for you will depend on your personal interests and career goals. It's important to research and thinks about the curriculum, campus culture, research opportunities, and career prospects offered by each program before making a decision.
