I am a Mechanical student at IIT Dhanbad. I can shed some light on my branch.
Mechanical is a very good branch at IIT Dhanbad. It witnesses very good placements, and the highest package is more than 20 LPA. One of our seniors got placed in Google for 72 LPA CTC, a few years back. Brands like Facebook, Google, and Microsoft visit the college, and many of them give opportunities to non-IT students.
IIT Dhanbad is known for its Mining branch. But as CSE is the craze of today, its cutoffs are quite high.
IIT Dhanbad is a wonderful college, totally deserving of the IIT tag. Don’t be misled by public opinion. IIT Dhanbad has a huge potential. Try to connect with some seniors in the branch of your choice to get a clearer perspective.
