Where to Find the Official Notification
IOCL uploaded the detailed notification PDF on its official portal on the same day the drive was announced. Before you touch the application form, open that PDF at least once. It carries the fine print on reservation, document checklist and disqualification clauses that a summary article like this one simply cannot cover in full, so treat it as the final word whenever something here and the PDF seem to disagree.
How the 470 Seats Are Split Across Disciplines
The bulk of the hiring is happening in Grade A, with smaller intakes at Grade A0 and Grade E0 level. Mechanical and Electrical engineering carry the largest share of seats this year, so candidates from those two branches have comparatively better odds purely on numbers.
| Grade | Discipline | Total | UR | EWS | OBC-NCL | SC | ST |
|---|---|---|---|---|---|---|---|
| A | Civil | 62 | 25 | 6 | 17 | 11 | 3 |
| A | Chemical | 16 | 11 | 1 | 2 | 1 | 1 |
| A | Electrical | 75 | 32 | 7 | 20 | 11 | 5 |
| A | Electronics & Communication | 32 | 13 | 4 | 8 | 6 | 1 |
| A | Mechanical | 118 | 49 | 12 | 32 | 19 | 6 |
| A | Instrumentation | 35 | 17 | 3 | 8 | 5 | 2 |
| A | Computer Science & IT | 22 | 11 | 2 | 4 | 3 | 2 |
| A | Law | 10 | 4 | 1 | 2 | 2 | 1 |
| A | Marketing | 41 | 17 | 4 | 11 | 7 | 2 |
| A0 | Quality Control (Chemistry) | 9 | 6 | 0 | 0 | 1 | 2 |
| E0 | Electrical | 14 | 8 | 1 | 2 | 1 | 2 |
| E0 | Mechanical | 21 | 12 | 1 | 4 | 2 | 2 |
| E0 | Safety | 15 | 8 | 1 | 2 | 2 | 2 |
| Total | 470 | 213 | 43 | 112 | 71 | 31 |
Key Dates You Cannot Afford to Miss
Application portals for PSU jobs tend to slow down badly in the last 48 hours because everyone waits until the deadline. Give yourself a buffer of at least three to four days before 3rd September so a payment failure or a document upload glitch doesn’t cost you the opportunity.

| Notification Released | 14th August 2026 |
| Online Application Begins | 14th August 2026 |
| Last Date to Apply | 3rd September 2026, 5:00 PM |

Who Can Apply: Eligibility Breakdown
Eligibility differs meaningfully depending on which post you are targeting, so read this section against the exact role you plan to apply for rather than assuming a generic engineering degree covers every category.
| Post | Qualification Required |
|---|---|
| Graduate Engineer (Grade A) — Chemical, Civil, CS/IT, Electrical, E&C, Instrumentation, Mechanical | B.Tech/BE or equivalent in the relevant branch |
| Officer, Marketing (Grade A) | MBA or PGDBA (AIU-equivalent) with a Marketing specialisation |
| Officer, Law (Grade A) | Graduate degree plus LLB, or a 5-year integrated LLB |
| Assistant Quality Control Officer (Grade A0) | Master’s degree (Chemistry background as specified) |
| Diploma Engineer (Grade E0) — Electrical, Mechanical, Safety | 3-year diploma in the relevant engineering stream |
A few things candidates frequently get wrong: final-year students can apply, but you must be ready to submit your final marksheet by 30th September 2026, and it needs to meet the minimum percentage cut-off. Degrees earned through distance education, correspondence or part-time modes are not accepted for this drive, so don’t waste an application fee if that applies to you. Law Officers and Assistant Quality Control Officers additionally need two years of relevant post-qualification work experience — this one is easy to miss if you’re only skimming the vacancy table.
Age Limit (as on 1st July 2026): Graduate and Diploma Engineers must be 26 or under, Marketing Officers 28 or under, and Law Officers and AQCOs 30 or under. The usual government relaxations apply on top of these: 3 years for OBC-NCL, 5 years for SC/ST, and 10 years for PwBD candidates.
Selection Process: How IOCL Will Actually Shortlist You
Don’t assume the interview carries as much weight as it does in many state PSU exams — at IOCL, the written test decides almost the entire outcome.
| Stage | Weightage |
|---|---|
| Computer-Based Test (CBT) | 85% |
| Group Discussion & Group Task | 5% |
| Personal Interview | 10% |
CBT Exam Pattern
The test runs for 150 minutes total and is split into two clearly separated sections, so pace yourself accordingly rather than rushing through Section A and running out of time on the domain-heavy Section B.
| Section | Topics | Questions/Marks | Time |
|---|---|---|---|
| A | Quantitative Aptitude (20), Logical Reasoning (15), English (15) | 50 | 60 minutes |
| B | Domain/Technical Knowledge | 50 | 90 minutes |
| Total | 100 | 150 minutes |
Every wrong answer costs you 0.25 marks, so guesswork on Section B’s technical questions can hurt more than it helps. The minimum qualifying marks also change based on category — UR/EWS/OBC candidates need 45% overall, SC/ST candidates need 40%, and PwBD candidates need 30%, with a separate sectional cut-off in each part of the paper.
Salary and Pay Scale
| Post | Basic Pay | Pay Scale | Approx. Annual CTC |
|---|---|---|---|
| Graduate Engineer / Marketing Officer / Law Officer | Rs. 50,000 | Rs. 50,000–1,60,000 | ~Rs. 18.4 Lakhs |
| Assistant Quality Control Officer | Rs. 40,000 | Rs. 40,000–1,40,000 | ~Rs. 14.8 Lakhs |
| Diploma Engineer | Rs. 30,000 | Rs. 30,000–1,20,000 | ~Rs. 11.1 Lakhs |
Selected candidates also sign a service bond — roughly Rs. 3 lakh for Grade A officers (reduced to Rs. 50,000 for reserved categories) and about Rs. 2 lakh for Grade A0/E0 roles (Rs. 35,000 for reserved categories). Factor this into your decision if you’re weighing multiple offers.
Application Fee
General, EWS and OBC-NCL candidates need to pay Rs. 1,000 online. SC, ST and PwBD candidates are fully exempted from the fee. Payment can be made through debit card, credit card, net banking, UPI or mobile wallets.
