While NIT Rourkela is a reputable institution, and a B.Sc. degree from there is generally accepted, you must check the official RRB notification for the specific position you're applying for. Each RRB notification clearly lists the required educational qualifications. The notification will specify the acceptable degrees, disciplines, and institutions. Simply having a B.Sc. from NIT Rourkela doesn't automatically guarantee eligibility; it needs to match the requirements of the particular RRB job opening.
