The Bongaigaon Refinery unit operates as part of the Corporation’s Refineries Division and engages apprentices under the Apprentices Act, 1961/1973, as a skill-building initiative for candidates from the region and across India.

Bongaigaon Refinery and the North East Candidate Catchment

Bongaigaon Refinery is located in Bongaigaon district, Assam, with legal jurisdiction for disputes falling under the local court at Chirang, as stated in the notification. Candidates from Guwahati can typically reach the Bongaigaon area by rail or road in a few hours, since the refinery town sits on the Northeast Frontier Railway network. This is editorial context, not part of the official notification — confirm travel timing and routes directly before the document verification dates. The candidate catchment for this recruitment typically includes diploma holders and graduates from technical institutes across Assam, Meghalaya, and neighbouring states, since Bongaigaon Refinery is one of the limited number of PSU refineries operating in the North East. Comparable regional institutions offering apprenticeship or entry-level technical training include Numaligarh Refinery and Oil India Limited, both located within Assam.

Important Dates

The application window for this recruitment runs for one month, and both the NAPS/NATS portal application and the Microsoft Forms submission must be completed within this period. The notification specifies exact opening and closing times, so candidates should not wait until the last day to submit.

Vacancy Details & Salary

Here’s the breakdown of posts, total vacancy and salary for your reference.

The notification confirms that stipend is payable as per the Apprentices Act 1961/1973 and Apprentices Rules 1992, along with the Corporation’s own guidelines, but does not state a fixed monthly figure. Based on comparable PSU refinery apprenticeship cycles in 2024–25, stipend for graduate and diploma-level trade or technician apprentices in central PSUs has generally fallen in the range applicable under the Apprentices Rules for the respective qualification category. This is editorial context, not part of the official notification — confirm the exact stipend amount with the Bongaigaon Refinery recruitment office.

2. In case of a tie, the candidate senior in age (date of birth) is ranked higher. If the date of birth also matches, the candidate with higher Matriculation marks is ranked higher.
3. Shortlisted candidates are called for document verification based on their position in the merit list and the number of seats notified for each trade.
4. Only candidates declared fit in the pre-engagement medical examination are considered for final engagement.

The notification specifically states that preference is given to candidates applying for apprenticeship training for the first time, over candidates who have already completed apprenticeship training in a different trade or discipline earlier.

How to Apply for IOCL Bongaigaon Refinery Apprentice Recruitment 2026

Should You Apply?

This recruitment suits candidates who already hold the exact qualification specified against a given trade code, are within the 18–24 age bracket (or eligible for age relaxation), and are looking for structured, PSU-based apprenticeship training rather than immediate confirmed employment. Candidates based in Assam or nearby North Eastern states are better positioned for the document verification stage and any physical fitness requirements tied to plant-based trades. It is not a strong fit for candidates holding higher qualifications such as BE/B.Tech, MBA, CA, LLB or MCA, since the notification explicitly excludes such candidates, nor for candidates with more than one year of job experience after acquiring their qualification.

Competition is likely to be high for graduate-level codes such as 101 and 108, given the relatively higher vacancy count and the broad pool of eligible B.Sc. and B.A./B.Sc./B.Com candidates, while diploma-based technician trades under Codes 104 to 107 may see comparatively fewer eligible applicants due to narrower branch specificity. Based on typical patterns in PSU apprenticeship engagement, apprentices completing this training often use it as a stepping stone toward diploma or degree-level technical roles in the oil and gas or manufacturing sector, though the Corporation itself places no obligation to offer employment after training. This is editorial context, not part of the official notification. One trade-off candidates should weigh is that this is a fixed-term apprenticeship, not a permanent post, and carries no claim to employment on completion.
