💡 Expert Tip
Apply for only one Academic/Engineering Stream that matches your qualification — ONGC explicitly states multiple applications will result in only the latest one being considered, and older ones get rejected outright, so double-check your stream choice before final submission since it cannot be changed later. If you hold an Applied Petroleum Engineering degree instead of a straight Petroleum Engineering degree, note you're eligible for only 7 of the 9 Petroleum Engineering vacancies (UR-3, OBC-2, SC-1, EWS-1), not all 9 — check this split carefully before applying under this stream. Also, ONGC has explicitly ruled out equivalent qualifications like AMIE where a Graduate Engineering Degree is specified, and BE/B.Tech in Chemical Sciences and Technology will not be accepted for the Chemical Engineering stream — make sure your exact degree title matches the essential qualification listed, not just the subject area.
