Which is better: CSE in NIT, Durgapur or metallurgy in NIT, Warangal?

I would like you to consider certain important things before making your decision-

• College- Without a doubt, NIT Warangal is ahead of NIT Durgapur in terms of faculty, infrastructure and hostel facilities.

• Subject - You need to choose your subject based on your interests. Without that you’ll either hate your profession or choose a completely different career path altogether. If you are into math, coding, logic and problem-solving, choose CSE. On the other hand, if you want to study materials, metals, extraction, etc, choose Metallurgy. 
• Profession - CSE will give you better opportunities in the IT sector. You might get a fat check, work for a good company, and live in metropolitans. As you know, IT jobs are basically office jobs.On the other hand, core Metallurgy jobs deal with steel plants, mines and such. You’ll end up working in a remote area if you choose a core job.The placements for CSE are overall much better than Metallurgy, across all engineering colleges. But if you have a passion for metallurgy, you might end up in a good brand or get selected for a government position. 
• Location- Both the places are culturally very different. Research a bit, and figure out which place’s food habits, climate, and culture suits you better.

According to me your college will last for 4 years. However, your branch will become an intrinsic part of your personality and profession. Unless you have an interest in Metallurgy or a good chance at sliding to another branch, choose CSE at NIT Durgapur.
