IOCL 2026 vacancy list: discipline-wise and category-wise

Mechanical leads with 118 posts, followed by Electrical (75) and Civil (62). Computer Science and IT has 22 posts in Grade A.

PwBD reservation is horizontal. 60 of the 470 posts are earmarked for candidates with benchmark disabilities — 55 in Grade A, 1 in Grade A0 and 4 in Grade E0 — spread across VI, HI, LD and multiple-disability categories. These are carved out of the totals above, not added to them. PwBD candidates are not eligible for the Safety post in Grade E0 because of the hazardous job role.

22 posts in Computer Science and IT. Of the 411 Grade A vacancies, CS & IT is the second-smallest engineering allocation — 11 UR, 2 EWS, 4 OBC (NCL), 3 SC and 2 ST. At that intake, the shortlisting cut-off sits far above the 45% qualifying mark, and a two- or three-mark gap decides the list.

Eligibility traps that get candidates rejected

Mechatronics and Robotics are not eligible

Any BE/B.Tech or diploma in a combined, integrated or inter-disciplinary branch — Mechatronics, Robotics and similar — is explicitly excluded, even if the syllabus overlaps with Mechanical or Electrical.

Higher degrees disqualify Grade E0 applicants

Diploma Engineer applicants holding BE, B.Tech, MBA, CA, CS, CMA, MCA or PhD are not eligible. Hiding a higher qualification leads to cancellation at any stage, including after joining.

59.99% counts as less than 60%

CGPA is converted using your institute's own formula and the resulting fraction is never rounded up. Carry the conversion certificate to document verification.

Dual and integrated degree rules differ

For a dual degree (two separate certificates), only the BE/B.Tech percentage counts. For an integrated M.Tech (single degree), the overall M.Tech percentage counts. Both marksheets are needed by 30 September 2026.

Age limit and application fee

Age is reckoned as on 1 July 2026. Only the Matriculation or Higher Secondary certificate is accepted as proof of date of birth.

Cut-off birth dates in the official notification: Graduate/Diploma Engineer — born on or after 01.07.2000 (Gen/EWS), 01.07.1997 (OBC-NCL), 01.07.1995 (SC/ST). Ex-servicemen relaxation follows extant Government of India guidelines.

Qualifying marks, shortlisting and final merit

You must clear both the sectional minimum and the overall minimum. Clearing the CBT does not by itself guarantee a GD/GT/PI call — shortlisting is by rank within your domain.

Category Min. Section A Min. Section B Min. overall Composite score

The written test carries 85 of every 100 composite marks. Practically, the CBT decides your selection — the interview stages exist mostly to filter, not to reorder the merit list.

IOCL 2026 syllabus: what to actually study

IOCL publishes a discipline-wise syllabus alongside the advertisement. Section A is common to every post; Section B follows your degree branch and tracks GATE-level fundamentals without the numerical depth.

Section A · 50 questions

General Aptitude

Quantitative Aptitude — number system, percentages, ratio and proportion, profit and loss, simple and compound interest, time-speed-distance, time and work, averages, mixtures, permutation and combination, probability, mensuration, data interpretation.

Logical Reasoning — series, coding-decoding, blood relations, direction sense, syllogism, seating arrangement, puzzles, statement and assumption, analogy, classification, data sufficiency.

Verbal Ability — reading comprehension, cloze test, para jumbles, error spotting, sentence improvement, fill in the blanks, synonyms and antonyms, idioms and phrases, vocabulary.

Section B · 50 questions

Domain Knowledge, by discipline

Mechanical — thermodynamics, fluid mechanics, heat transfer, strength of materials, theory of machines, manufacturing, IC engines, refrigeration, industrial engineering.

Electrical — circuit theory, electrical machines, power systems, control systems, measurements, power electronics, electromagnetic fields.

Computer Science & IT — data structures, algorithms, operating systems, DBMS, computer networks, computer organisation, theory of computation, software engineering, programming in C, cyber security basics.

Civil — structural analysis, RCC and steel design, geotechnical, fluid mechanics, transportation, environmental engineering, surveying, construction management.

Chemical, E&C, Instrumentation, Law, Marketing and Chemistry follow their own core-subject lists in the official syllabus PDF.

The topic lists above are compiled from the official syllabus document and past IOCL CBT papers. Always cross-check against the syllabus PDF hosted with the advertisement on iocl.com.

Reading the syllabus is step one. Attempting it under a timer is step two.

Most CS & IT candidates know the subjects. What separates the shortlist is finishing 50 aptitude questions in 60 minutes without leaking marks to negative marking, then switching cleanly into 50 domain questions. That is a trained skill, not a knowledge gap — and the only way to build it is repeated full-length attempts in the real format.

How to apply for IOCL Recruitment 2026

Applications are accepted only through www.iocl.com. Once you click Complete Registration, nothing can be edited — not your category, not your name spelling, not your email.

01
Prepare your scans first.

Photograph 4.5 × 3.5 cm taken in April 2026 or later (200 × 230 px, 20–50 KB), signature in black ink (140 × 60 px, 10–20 KB) and left thumb impression (240 × 240 px at 200 DPI, 20–50 KB). All in JPG or JPEG. A signature in capital letters is rejected.

02
Register on the portal.

Go to iocl.com → Latest Job Opening → Apply Online → New Registration. Save the provisional registration number and password the system generates. The email ID and mobile number you enter cannot be changed later, so use ones you will keep active for at least a year.

03
Fill the form and capture a live photo.

Besides the uploaded photograph, the portal captures a live photo through your webcam or via a QR code on your phone. Your appearance on GD/GT/PI day should match both. Use Save and Next to preserve progress.

04
Pick three exam city preferences.

Choices are final once submitted and cannot be changed. IOCL may still allot a different centre based on capacity.

05
Preview, pay, and save the PDF.

Verify everything on the Preview tab before clicking Complete Registration, then pay ₹1,000 + GST (SC/ST/PwBD exempt). No e-receipt means the payment failed — log back in and retry. Keep the generated PDF; do not post it to IOCL.

06
Download the admit card from 15 September.

Carry the call letter plus an original and photocopy of a valid photo ID — PAN, Passport, permanent driving licence, Voter ID, Aadhaar or an institutional ID. Ration cards and learner's licences are not accepted. Reach before gate-closure time; latecomers are turned away.

A 40-day plan for the 24 September CBT

You have roughly six weeks from the notification date. Here is how serious candidates should split them.

Days 1–18

Cover the domain core

Section B is 50 of 100 marks and is where the spread happens. Revise your five highest-weight core subjects first, at concept-and-formula level rather than derivation level. IOCL asks broad, application-flavoured questions, not GATE-depth numericals.

Days 19–32

Drill aptitude to speed

50 aptitude questions in 60 minutes leaves 72 seconds each. Practise DI sets, arithmetic shortcuts and reading comprehension against a timer daily. This section is the cheapest place to gain 8–10 marks.

Days 33–40

Full mocks and error log

Take at least six full 150-minute mocks in the real sectional order. With −0.25 negative marking, track your accuracy: below 70% accuracy, guessing costs more than it earns. Maintain an error log and revise only from it in the last four days.

Frequently asked questions

How many vacancies are there in IOCL Recruitment 2026?

470 Executive vacancies in total — 411 in Grade A, 9 in Grade A0 (Quality Control) and 50 in Grade E0 (Diploma Engineer). Mechanical has the most posts at 118, followed by Electrical (75), Civil (62) and Marketing (41). Computer Science and IT has 22 posts.

Is a GATE score required for IOCL Recruitment 2026?

No. This recruitment runs entirely on IOCL's own Computer Based Test. Shortlisting for GD, GT and PI is done by ranking CBT marks out of 100 within each domain. A GATE score gives no advantage here.

Can final-year students apply for IOCL 2026?

Yes, provided you can produce the final degree or marksheet by 30 September 2026 and your aggregate across semesters declared so far meets the minimum percentage. If your final aggregate falls below the cut-off later, you will not be allowed to join.

Are Mechatronics or Robotics graduates eligible?

No. Combined, integrated or inter-disciplinary branches such as Mechatronics and Robotics are explicitly excluded. Your degree certificate must name one of the disciplines listed in the advertisement — for example, Computer Science and Engineering (Data Science) is accepted for the CS & IT domain, but a hybrid mechanical-electronics branch is not.

Can I apply for more than one post?

One application for one post only. If multiple applications are submitted, only the latest is considered and the earlier ones are rejected. Appearing more than once in the CBT for the same post cancels your candidature.

Is work experience mandatory?

Only for two posts. Law Officer needs 2 years of post-qualification legal practice and Assistant Quality Control Officer needs 2 years in petroleum, petrochemical, polymer or fertiliser lab testing or an NABL-accredited chemical testing lab, both as on 30 June 2026. Internships, teaching and short-term training do not count. Graduate and Diploma Engineer posts need no experience.

Can I change my exam centre or category after applying?

No, neither. Centre preferences and category are final once submitted, and no request for change is entertained. Filling the wrong category means losing the relaxation and reservation attached to it, so verify carefully on the Preview tab before completing registration.

What happens after I clear the CBT?

Shortlisted candidates go through document verification, then Group Discussion, Group Task and Personal Interview. Final selection also requires clearing the pre-employment medical examination. Selected candidates sign a three-year service bond and can be posted anywhere in India.
