My very good friend was a student placement convener of mining engineering in NIT Raipur, therefore I have a fair idea about how it works.
Although the intake is 77, which is far more compared to any other colleges, the job opportunities are not enough for all the admitted students. Big brands such as Adani, CIL, VEDANTA do come in for the campus recruitment but they are not sufficient for all and also their eligibility criteria and other requirements do not fit all.
Talk to the seniors in the college to find out more about the actual placement scenario at the institute.
