What is the Selection Process for Oil India Recruitment 2026?

| Grade A: CBT | 100 marks, 1 hour 30 minutes, sole basis of the merit list |
| Grade A: Skill Test | 100 marks, qualifying only, 50 marks needed, called in a 1:2 ratio |
The CBT qualifying mark is 50 out of 100 for UR, OBC-NCL and EWS, and 40 out of 100 for SC, ST and PwBD (Grade A: 50 for UR and OBC-NCL, 40 for PwBD). The final score for Grades C and B is the CBT mark times 0.85, plus the interview mark out of 15. No other scaling or conversion may be applied to the interview marks. Failing the Grade A skill test disqualifies you, whatever your CBT score. The skill test is Shorthand and Transcription for Confidential Secretary, and Translation, Essay, Writing, Computer Application and Bilingual Typing for Hindi Officer. Originals are checked at the interview or skill test; a medical test follows. A candidate declared medically unfit has the appointment cancelled.
