You can get into BARC through GATE or its own entrance test as these are the only channels/ways you can get recruited in BARC as recruitment of Scientific Officers is through two major programmes – OCES (Orientation Course for Engineering Graduates and Science Post Graduates) and DGFS (DAE Graduate Fellowship Scheme). Also, this is a PSU which provides vacancies not the college which gives admission in any course.

To know about its eligibility criteria, you can go through the below link -
