Bad. Even very bad, depending on the year.
Unlike other branches, chemical engineering doesn't have a fixed influx of companies year by year. Say for one year, 30 students might get placed, the next, only 10.
Overall, the chances are bleak. I'd look elsewhere or at other branches at NIT Raipur if I were you.

For Chemical Core companies do not come for campus selections so it is not much good. For its reviews you can go through with given below link.
