How promising are the branches other than CSE in NIT Jamshedpur? I got metallurgy in NIT J and am really worried.

I can completely understand your fear. I am an NIT Jamshedpur alumni from the Metallurgy branch, and here are some details about this course-

1. Metallurgy has a lot of scope in the field of research.
2. Some professors are really good and helpful. But don’t depend too much on them because you’ll have to do plenty of self-study.
3. Metallurgy placements are good at NIT Jamshedpur. You’ll get opportunities for both, core and non-core jobs.
4. Core companies like Vedanta Group, Tata Steel, JSW, JSL, etc. visit the campus with good CTC offers.
5. Non-core companies offer high packages. 
6. Jamshedpur has plenty of steel companies. So you’ll find many of them visiting the campus during placements, offering good CTCs.
7. You’ll get industrial exposure. The Metallurgy department organizes industrial visits.
8. You’ll get the chance to do your projects/internships in renowned organizations like Tata Steel, Tata Motors and National Metallurgical Laboratory among others.

Work hard but also enjoy your B.Tech life to the fullest. Also, don’t worry, Metallurgy from NIT Jamshedpur is a good choice, especially for future prospects.
