Oil and Natural Gas Corporation Limited (ONGC), India's Maharatna energy major, has released Advertisement No. 2/2026 (R&P) to recruit 52 Geologists and Engineers at the E1 level through a Computer Based Test (CBT).

Selection Process

ONGC selects candidates in three stages:

1. Computer Based Test (CBT): An objective-type test covering your Concerned Subject, General Awareness, Aptitude, and English Language, to be completed in 2 hours.
2. Personal Interview: Based on your CBT score, you are shortlisted for interview in a 1:5 ratio.
3. Medical Examination: You must clear ONGC's Medical Examination of Employees Rules (available on the ONGC website) before you get the final offer of appointment.

Mere appearance in the medical examination does not guarantee selection — only candidates declared medically fit will get the offer of appointment. In case of a tie in total marks, the candidate scoring higher in the CBT is ranked senior, and if still tied, the older candidate is ranked senior.
