₹1,000 + GST for General/EWS/OBC(NCL) candidates, paid online. SC/ST/PwBD candidates are fully exempted. The fee, once paid, is non-refundable under any circumstances.

How to Apply

1. Go to iocl.com, open 'Latest Job Opening', and click 'Apply Online' (direct link: iocl.com/latest-job-opening).
2. Register with your basic details, then fill in your educational, personal, and category details.
3. Upload your photograph, signature and other required documents in the specified format.
4. Pay the application fee online (if applicable) and submit the form; keep a printout of the submitted application and e-receipt for your records.

How Are Candidates Selected

The Computer Based Test (CBT) has 100 objective multiple-choice questions in two sections — Section A (General Aptitude: Quantitative Aptitude, Logical Reasoning, Verbal Ability — 60 minutes) and Section B (Domain Knowledge, 50 questions — 90 minutes), with 0.25 marks deducted per wrong answer. To qualify in CBT you need a minimum of 45% overall (40% in each section) for General/EWS/OBC(NCL), 40% overall (35% per section) for SC/ST, or 30% overall (25% per section) for PwBD. Shortlisted candidates then go through Group Discussion (GD) and Group Task (GT), followed by a Personal Interview (PI). The final merit list is a weighted composite score: CBT 85%, GD/GT 5% (minimum 40% to pass), PI 10% (minimum 40% to pass).

Why This Job Matters

IOCL is India's largest oil-marketing PSU and a Maharatna company, running the country's refining, pipeline, and fuel-retail network. An Executive-cadre entry here is one of the most sought-after PSU openings in the energy sector, combining Grade A/A0/E0 pay scales with PSU-level job security and a defined promotion ladder — which is why 470 vacancies spread across five disciplines draws heavy competition every cycle.

The FreshersLike Take

This is a strong fit if you hold the exact branch/specialisation named in the notification and can comfortably clear a CBT plus GD/PI process — IOCL's shortlisting is fairly literal about the 'eligible discipline as mentioned on degree certificate,' so a borderline or combined-discipline degree (e.g., Mechatronics, Robotics) won't be considered no matter how similar it looks to your college's syllabus. Think twice if your degree name doesn't exactly match one of IOCL's listed disciplines, or if you're not ready for a 3-year service bond (₹2–3 lakh for General category, ₹35,000–50,000 for reserved categories) that locks you in after selection. Practical tip: get your CGPA-to-percentage conversion certificate from your institute before you apply — IOCL rounds down (59.99% is treated as under 60%), so this one document can decide your eligibility.

Documents Required

• Final degree/diploma certificate and marksheets showing the exact discipline name
• CGPA-to-percentage conversion certificate, if your result is on a grading scale
• Category certificate (SC/ST/OBC-NCL/EWS/PwBD) in the prescribed Central Government format, where claiming reservation
• Work-experience certificates for Law Officer applicants (minimum 2 years' post-qualification legal experience)
• Passport-size photograph and signature scanned to the specification given in the notification

No. The notification explicitly excludes combined/integrated/inter-disciplinary degrees such as Mechatronics or Robotics from the Graduate Engineer posts.

Is the application fee refundable if I don't appear for the CBT?

No. IOCL states the fee is non-refundable 'under any circumstances,' and chargebacks cannot be claimed either.

What is the exact last date to apply?

3 September 2026, up to 5:00 PM. IOCL advises applying well before the deadline to avoid last-minute website load issues.

Do Diploma Engineer candidates with a BE/B.Tech or MBA remain eligible?

No. Candidates holding professional higher qualifications such as BE/B.Tech, MBA, CA, CS, CMA, MCA or PhD are barred from the Diploma Engineer (Grade E0) posts.

Yes — 3 years, with a bond amount of ₹2 lakh (General category, Grade A) or ₹3 lakh (Grade A0/E0), reduced to ₹35,000–50,000 for EWS/OBC(NCL)/SC/ST/PwBD candidates.
