Which is better at NIT Raipur Mechanical or Civil?

Both branches offer enough opportunities and scope in their respective fields. However, choosing one between these two will depend on your own preferences. 

Placement-wise, Mechanical is slightly better than Civil at NIT Raipur. But that certainly does not mean that Civil students don’t get any kind of opportunities. One of my friends did his internship at Delhi Metro (DMRC) and that opened many doors of opportunities in both public and private sectors. As a civil engineer, you can contribute your services towards the nation's development along with public services. 

Here is a slight comparison of placement statistics of these branches

In my opinion, Civil Engineering seems to be a better option than Mechanical. This is because there are huge vacancies in the public sector so the demand for civil engineers is slowly increasing. However, one must bear in mind that NIT Raipur has very few core companies coming for placements. Some of them that have visited in the past are L&T, SPCL, S K Samantha, Buildkraft, and PSUs like BPCL, HPCL, and CIL.

Ultimately, choose the branch that suits your inclinations and future prospects.
