We cannot line IOCL Apprentice/Engineer up against other exams yet
This does not mean IOCL Apprentice/Engineer shares nothing with the exams you are preparing for — only that we have not loaded a chapter-by-chapter syllabus we can compare against, so we will not guess. We compare 0 exams whose official syllabus we have traced to the conducting body, and this one is not among them yet.

FAQsPending verification
Does IOCL recruit engineers through GATE?
IOCL has used GATE historically, but the live 2026 executive recruitment does not. Advt. No. IOCL/CO-HR/RECTT/2026/01 uses IOCL's own 100-question CBT for all thirteen routes. Follow the live notice, not the historical GATE route.
Is there an exam for the IOCL apprentice notifications?
No. The Marketing Division Western Region notification says 'There will be no written Test/Interview' and the Paradip Refinery notification says 'There shall be No Written Test.' Candidates are ranked purely on the percentage of marks in the prescribed qualification for the trade applied for, then called for document verification and a pre-engagement medical.
Can a B.Tech holder apply for an IOCL Trade or Technician Apprentice seat?
No. The Marketing Division notification states that candidates possessing higher professional qualifications such as B.E./B.Tech., MBA or equivalent, MCA/CA/ICWA, LLB or any such equivalent qualification - or pursuing one that will be completed on or before joining - shall not be eligible, and a declaration is taken at the time of joining.
How much of the Engineer selection is the written test?
85%. The 2026 merit list weights CBT at 85%, Group Discussion and Group Task together at 5%, and Personal Interview at 10%. A candidate must qualify the applicable CBT section and overall thresholds, the later components and the composite score.
Does completing an IOCL apprenticeship lead to a job at IOCL?
No. The Paradip Refinery notification states that on completion of the apprenticeship period the Corporation shall have no obligation to offer employment, nor can an apprentice claim a right to employment on the grounds of completing the apprenticeship.
Final eligibility and dates are always subject to the latest official notification. Content marked “Pending verification” is not presented as verified advice.
