Introduction
For Mechanical engineers in India, the Graduate Aptitude Test in Engineering (GATE) is not just an exam for higher studies — it’s a gateway to prestigious Public Sector Undertakings (PSUs).
Top organizations like ONGC, IOCL, NTPC, BHEL, GAIL, BPCL, HPCL, and others recruit mechanical engineers primarily through GATE scores. A good rank can secure a high-paying, secure, and respected career in industries ranging from energy and oil & gas to power, aviation, and infrastructure.
This guide explains everything about PSU recruitment via GATE: eligibility, selection process, cutoff trends, salary structures, and preparation strategies.
Why PSUs Recruit Through GATE?
- Merit-based filtering: GATE offers a common, standardized technical evaluation.
- Reduced recruitment load: PSUs avoid conducting their own exams.
- Level playing field: Engineers across India are judged on the same parameters.
- Benchmark for skills: GATE syllabus overlaps with core engineering required in PSUs.
List of PSUs Recruiting Mechanical Engineers Through GATE
PSU | Typical Role | GATE Paper | Salary (Approx.) | Highlights |

ONGC | Graduate Trainee (ME) | ME | ₹15–20 LPA CTC | Oil exploration, rigs, offshore |
IOCL | Assistant Officer / Engineer | ME | ₹12–16 LPA | Refineries, energy, pipelines |
NTPC | Executive Trainee (ME) | ME | ₹11–15 LPA | Power plants, turbines |
BHEL | Engineer Trainee (ME) | ME | ₹10–12 LPA | Power & heavy machinery |
GAIL | Executive Trainee (ME) | ME | ₹10–12 LPA | Gas pipelines, petrochemicals |
BPCL / HPCL | Graduate Engineer | ME | ₹12–14 LPA | Oil & Gas downstream |
NPCIL | Executive Trainee | ME | ₹9–12 LPA | Nuclear reactors |
POWERGRID | Engineer Trainee | ME | ₹11–13 LPA | Transmission & grids |
Eligibility Criteria
- Degree: Full-time B.E./B.Tech in Mechanical Engineering.
- Minimum Marks: 60–65% (varies per PSU).
- GATE Paper: Mechanical Engineering (ME).
- GATE Validity: Score valid for 3 years, but PSUs usually accept only current year’s score.
Recruitment Process
- GATE Exam → Written national-level exam (MCQs + NATs).
- Shortlisting by PSUs → Based on GATE score (normalized).
- Group Discussion / Written Test → (Some PSUs conduct GD/GT).
- Personal Interview → Focuses on technical & HR questions.
- Final Selection → Based on combined weightage.
Weightage System (Typical)
Stage | Weightage |
---|---|
GATE Score | 75–85% |
Group Discussion / Written Test | 5–10% |
Personal Interview | 10–15% |
In some PSUs (like ONGC, NTPC), GATE alone is enough, while others (IOCL, HPCL) add GD/PI.
