About Indian Oil Corporation Limited
Indian Oil Corporation Limited is a Government of India undertaking and a Fortune “Global 500” company engaged in refining, transporting and marketing petroleum products. The Guwahati Refinery Unit is inviting applications under the Apprentices Act, 1961/1973 to build technical and administrative skills among candidates through structured apprenticeship training. For candidates in Assam and neighbouring states, this notification offers exposure to plant operations, maintenance and administrative functions inside one of India’s largest refining establishments. Candidates can read more about IOCL and its other units on the official IOCL website and on the Indian Oil Corporation recruitment page on this portal.
Local Context for Assam and North East Candidates
Guwahati Refinery is located at Noonmati, Guwahati, Assam, and its apprentice intake typically draws candidates from Assam, Meghalaya, Tripura, Nagaland and other North Eastern states. Candidates travelling from Shillong, Jorhat, Dibrugarh, Tezpur and Silchar for Document Verification generally reach Guwahati by road or rail, with Noonmati and Guwahati railway stations located close to the refinery. IOCL also runs apprentice programmes at its Digboi and Bongaigaon units in Assam, and candidates from this region often track those notifications together with the Guwahati one. Given the 102 seats on offer and the reservation norms applicable to the state, ST and OBC(NCL) category candidates from Assam are expected to form a sizeable share of the applicant pool this cycle. Candidates should also check latest Assam government and PSU jobs for other current openings in the region.
Important Dates
The application window for this recruitment is fixed and applies to all 11 trade codes listed in the notification. Candidates should complete both the NAPS/NATS registration and the Microsoft Form before the closing date, since either step alone does not complete the application.

Should You Apply?
This recruitment suits candidates who have completed Class XII, ITI (Fitter), or a relevant Diploma or Graduation degree in the exact discipline notified for a chosen code, and who fall within the 18 to 24 age bracket, with relaxation for reserved categories. It also suits candidates based in or near Assam and the North East, since Document Verification takes place at the Guwahati Refinery itself. This opportunity is not a good fit for candidates who already hold a BE/B.Tech, MBA, CA, LLB or MCA, or those with more than one year of job experience after their qualification, since the notification excludes such candidates. With 102 seats spread across 11 disciplines and selection based purely on qualifying marks, competition is expected to be high for B.Sc.-based Codes 101 and 103, and for the single-seat Codes 109 and 111. Based on typical PSU apprentice cycles, candidates who complete this training generally move on to industrial ITI/Diploma-linked roles or further apprenticeship elsewhere, though IOCL gives no employment guarantee after training. Candidates should weigh this training-only nature before applying, since no HRA or accommodation is provided either.
FAQs — IOCL Guwahati Refinery Apprentice Recruitment 2026
Does IOCL Guwahati Refinery guarantee a job after apprenticeship?
