About Indian Oil Corporation Limited, Barauni Refinery
Indian Oil Corporation Limited is a Government of India undertaking and a Fortune Global 500 company. The corporation runs this apprentice engagement at its Barauni Refinery unit under the Apprentices Act, 1961/1973, as part of its skill building initiative for the country. Barauni Refinery is located in Begusarai district, Bihar. Candidates should visit www.iocl.com for the complete notification and future updates on this recruitment.
Public sector refineries such as Indian Oil regularly run apprentice cycles with vacancy counts in the range of a few hundred, split across chemical, mechanical, electrical and clerical trades. Based on comparable PSU refinery apprentice cycles in recent years (this is editorial context, not part of the official notification; candidates should confirm specifics with the hiring office), candidates with a B.Sc background in Physics, Chemistry and Mathematics often face the highest competition, since the Attendant Operator, Chemical Plant trade alone carries 237 of the 432 seats in this notification. Diploma holders in Mechanical, Electrical and Instrumentation Engineering compete for a comparatively smaller pool of seats, which can mean a shorter merit list and faster document verification. Candidates from other states are also eligible, since seats are governed by all-India reservation norms rather than a domicile requirement.
Important Dates
The notification lists key dates for the application process and document verification. Candidates should complete both steps of the application before the last date, since late submissions will not be considered.
| Event | Date |
|---|---|
| Opening of online application on NAPS/NATS portal and Microsoft Forms | 29.06.2026 |

Selection Process

- A merit list is prepared based on the percentage of marks obtained in the prescribed qualification, considering the aggregate of all years or semesters.
- In case two or more candidates have the same percentage, the candidate senior by date of birth is ranked higher; if the date of birth also matches, the candidate with a higher percentage in Matriculation is ranked higher.
- Shortlisted candidates are called for document verification.
- Candidates must clear a pre-engagement medical fitness examination.
- Only candidates found fit in the medical examination, and whose documents are in order, receive the offer of engagement.
One practical insight from the notification: filling of seats depends entirely on the availability of suitable candidates, so vacancies in a category can remain unfilled if enough eligible candidates do not apply or do not clear document verification.

Should You Apply?
This recruitment suits candidates who have completed the qualifying course for one of the eleven trades, meet the age limit as on 30 June 2026, and are open to a fixed-term apprenticeship without a guarantee of regular employment afterward. It is a reasonable option for freshers seeking hands-on exposure to refinery operations, since the corporation places no obligation of absorption on completion of training. Candidates already holding a higher professional qualification such as B.Tech, MBA, CA or MCA are not eligible, and this recruitment does not suit candidates seeking long-term job security. Given that the Attendant Operator, Chemical Plant trade alone carries 237 of the 432 seats, competition among B.Sc candidates is likely to be high. Based on typical patterns at other PSU refineries (this is editorial context, not part of the official notification), candidates who complete this apprenticeship often use the certificate and hands-on experience to qualify for technician-level openings in the oil and gas sector later. Candidates should weigh the value of this training against the absence of any employment guarantee before applying.
