What Are PSU Exams and Public Sector Undertakings?
PSU exams are recruitment tests for jobs in Public Sector Undertakings, government-owned companies where the central or state government holds a majority stake, usually at least 51 percent. These exams fill engineering and non-engineering posts across Group A, B, and C through written tests, GATE scores, and interviews.
A Public Sector Undertaking, or PSU, is a company in which the government owns a controlling share. It may be owned fully or partly by the central government, a state government, or both. In most central PSUs the central government holds at least 51 percent of the equity. PSUs are also called public sector enterprises, government-owned corporations, or nationalised firms, and they recruit regularly across almost every industry.
PSUs are broadly divided into central PSUs and state PSUs. The Department of Public Enterprises also classifies profit-making central PSUs into three special categories based on their financial strength and autonomy:
- Maharatna
- Navratna
- Miniratna Category I
- Miniratna Category II
As of 2026 there are 14 Maharatna CPSEs, with Hindustan Aeronautics Limited becoming the 14th in October 2024, and 26 Navratna CPSEs, after IRFC and IRCTC were granted Navratna status in March 2025. Maharatna companies can invest up to Rs 5,000 crore in a single project without government approval, Navratna up to Rs 1,000 crore, Miniratna Category I up to Rs 500 crore, and Category II up to Rs 300 crore.

PSU jobs attract lakhs of applicants because they offer strong job security, attractive pay under the industrial dearness allowance structure, pensions and retirement benefits, and social reputation. As government-owned enterprises, PSUs provide stable careers, medical cover, housing, and clear promotion paths that private-sector roles rarely match, making them a top choice for engineers.
PSU employment in India is attractive for several reasons, from long-term stability to a respected professional standing.
Job Security
PSU jobs offer some of the most secure employment in India. Candidates are hired on both permanent and contract bases, but permanent government-sector roles come with lifetime security that many applicants work hard to achieve.
Pay Scale
Employees in PSU roles are paid well through their tenure, with additional perks such as allowances, medical cover, and a retirement pension. These long-term benefits and the added job security are why many candidates prefer PSU jobs over private-sector employment.
Reputation
Working in India's public sector carries a strong professional reputation. Because PSUs are owned by the government and often operate at a national scale, their pay scales are generally higher than comparable state-government roles, and candidates can apply for a wide variety of positions.
The following are some of the positions commonly available in PSU recruitment:
| Common PSU Posts 2026 | Other PSU Posts 2026 |
|---|---|
| Manager | Clerk |
| Scientist | Technical Assistant |
| Non-Technical Assistant | Human Resources |
| Doctor | Nurse |
| Pharmacist | Medical Officer |
| Engineer | Diploma Apprentice |
| Executive | Secretary |
| Head of Department | Assistant Engineer |
| Technician | Trainee |
| Junior Engineer | Consultant |
What Is the Eligibility for PSU Recruitment?
Eligibility varies by post because PSUs hire across many grades. General requirements include a minimum age of 18 years and an educational qualification ranging from Class 10 or ITI to a diploma, graduate, or postgraduate degree. Engineering executive posts additionally require a valid GATE score, while clerical roles use separate selection tests.
Because the PSU sector advertises vacancies across many fields and grades every year, the qualifying conditions differ from one post to another. The following are the general requirements for most PSU jobs:
- The candidate must generally be at least 18 years old, with upper age limits varying by post and category.
- An educational qualification of Class 10, Class 12, ITI, diploma, undergraduate, or postgraduate degree is required, depending on the role.
- A valid GATE score is required for most engineering executive and officer postings.
Candidates should read each notification carefully before applying. The public sector includes permanent, temporary, and contract posts across Group A, B, and C, so it is important to review the job description, eligibility, pay scale, and selection process for the specific position.

GATE, the Graduate Aptitude Test in Engineering, is conducted by IISc and the IITs for the Ministry of Education. GATE 2026 was held in February 2026 with results on 19 March 2026, and scores stay valid for three years. Over 30 PSUs including IOCL, NTPC, ONGC, and NPCIL shortlist engineers using these scores.
GATE is a national-level examination conducted by IISc Bengaluru and the IITs on behalf of the National Coordination Board under the Ministry of Education. PSUs use the GATE score, not the raw marks, to shortlist candidates for engineering executive and officer posts. Non-engineering roles such as clerical or administrative positions use separate written tests, aptitude papers, group discussions, and interviews.
Cut-offs vary by PSU: top recruiters like IOCL, ONGC, and NTPC typically require very high scores, while others such as BHEL, NPCIL, and HAL accept a wider range. For example, NPCIL advertised 330 Executive Trainee posts for its 2026 cycle, shortlisting candidates on the basis of valid GATE 2024, 2025, or 2026 scores followed by an interview.
How Should You Prepare for PSU Exams?
Start by studying the official notification and syllabus for your target PSU, then build a realistic timetable. Focus on core engineering subjects for GATE-based posts and on quantitative aptitude, reasoning, and general awareness for non-GATE tests. Practise mock papers and previous years, make concise revision notes, and track official websites for updates.
A strategic, consistent approach is essential for PSU exam preparation. The tips below can help you plan effectively and stay on track.

- Use mock tests to identify strong and weak areas and adjust your plan.
- For GATE-based posts such as IOCL, BPCL, and HPCL, prepare separately for the GATE exam.
- Visit the PSU's official website regularly to stay updated on notifications.
