Last Updated: 16 August 2026
Indian Oil Corporation Limited (IOCL) has released its Executive Recruitment 2026 notification for 470 posts across Graduate Engineer, Officer (Marketing), Officer (Law), Assistant Quality Control Officer, and Diploma Engineer roles. This is a direct, Non-GATE recruitment — selection runs entirely through IOCL's own Computer Based Test, not through your GATE score. Online applications are open from 14 August to 3 September 2026, and the CBT is tentatively set for 24 September 2026. Full eligibility, discipline-wise vacancies, fee details, and the exact selection weightage are covered below.
Direct CBT vs GATE-Based Entry — Why This Matters
📌 This is not a GATE-score recruitment. IOCL is conducting its own Computer Based Test on 24 September 2026, open to eligible candidates whether or not they've taken GATE. Several competitor articles blur this point by listing GATE-year references next to this notification, which leaves readers unsure which route actually applies to them. To be direct: if you meet the qualification and age criteria below, you can apply and sit for this CBT — no GATE score, card, or category is required anywhere in this process.

Application Fee — A Note on Conflicting Reports
⚠️ Fee figures conflict across sources. Most reports confirm ₹1,000 + GST for General/EWS/OBC(NCL) candidates, with SC/ST/PwBD exempted — this is the figure used below. A small number of other sites report no fee at all for this drive. Since the majority and more detailed sources agree on ₹1,000+GST, treat that as the reliable figure, but confirm the exact amount on the payment page itself before finalizing your application.
| Category | Fee |
|---|---|
| General / EWS / OBC(NCL) | ₹1,000 + GST |
| SC / ST / PwBD | Exempted |
Selection Process & CBT Pattern
Selection combines four stages — the CBT, Group Discussion, Group Task, and a Personal Interview — with the final merit built as a weighted composite score: CBT 85% + GD/GT 5% + Personal Interview 10%.
The CBT has 100 objective questions (1 mark each) with 0.25 negative marking for every wrong answer, split into two sections: Section A – General Aptitude (60 minutes: Quant 20 questions, Logical Reasoning 15, Verbal Ability 15) and Section B – Domain Knowledge (90 minutes, 50 questions). Qualifying marks: General/EWS/OBC(NCL) need 40% per section and 45% overall; SC/ST need 35% per section and 40% overall; PwBD need 25% per section and 30% overall.
Section A's Quant, Reasoning, and Verbal Ability portion follows almost the same pattern used in SSC-level competitive exams, so practicing a general aptitude test built around that structure is a smart, low-effort way to warm up before you get into IOCL-specific domain revision. You can build that base with our SSC CGL Full Length Mock Test series, which covers the same Quant-Reasoning-Verbal combination this CBT tests in Section A.
Salary & Pay Scale
| Grade | Pay Scale | Approx. CTC |
|---|---|---|
| Grade A | ₹50,000 – ₹1,60,000 | ₹18.4 Lakh/year |
| Grade A0 | ₹40,000 – ₹1,40,000 | ₹14.8 Lakh/year |
| Grade E0 | ₹30,000 – ₹1,20,000 | ₹11.1 Lakh/year |
Selected candidates must sign a 3-year service bond — ₹3 lakh (General, Grade A) or ₹50,000 (reserved categories, Grade A); ₹2 lakh (General, Grade A0/E0) or ₹35,000 (reserved categories). Postings can be anywhere in India, including overseas offices.
