About NHPC
NHPC Limited, formerly known as National Hydroelectric Power Corporation, was incorporated in 1975 as a Central Government enterprise to develop hydro power in India. Since then, it has grown into the country's largest central utility for hydro power development, holding Miniratna status since 2008.
NHPC is mandated to plan, promote, and organise efficient power development across conventional and non-conventional sources in India and abroad. From its early projects such as Baira Siul, Loktak, and Salal, the company has expanded into a major player behind India's power infrastructure.
NHPC's openings on Jobaaj typically include roles for engineering and executive trainees, along with experienced professionals in civil, electrical, and mechanical engineering, finance, and operations. As a central PSU, NHPC values technical competence, discipline, and commitment to long-term infrastructure projects.
NHPC hiring process
1. Online application
Candidates apply through Jobaaj or NHPC's official recruitment notifications, which specify eligibility for engineering, executive, or trainee positions. Notifications typically list vacancies by discipline and project region.
2. GATE score or written test screening
For engineering trainee roles, NHPC typically shortlists candidates using their GATE score or a written examination, in line with common practice at power sector PSUs. Non-technical roles may instead go through a separate written aptitude test.
3. Document verification
Shortlisted candidates undergo verification of educational qualifications, category certificates, and identity documents. This stage is usually conducted at a designated NHPC office or through an online upload process.
4. Technical interview
A panel of senior engineers assesses core technical knowledge in civil, electrical, or mechanical engineering, along with awareness of hydro power project processes. Candidates are also asked about academic projects or prior field experience.
5. HR or personality round
A discussion with HR and senior management evaluates communication, adaptability, and suitability for postings across remote project sites. This round often covers willingness to work at hilly or difficult terrain locations.
6. Medical examination and offer
Selected candidates undergo a medical fitness check before receiving an appointment letter and joining a structured training programme. Training typically familiarises new joiners with project site operations before formal placement.
NHPC interview rounds
NHPC's interview process typically runs four to five stages for engineering and executive positions.
Round 1: GATE score or written test screening
Eligibility is typically screened using the candidate's GATE score or a written test covering core engineering subjects relevant to hydro power. This stage determines the shortlist proceeding to verification and interviews.
- Civil, electrical, or mechanical engineering fundamentals
- General awareness of India's hydro power sector
Round 2: Document and eligibility verification
A verification stage checks degree certificates, category proofs, and other eligibility documents against the application. Discrepancies at this stage can affect a candidate's continued eligibility for the role.
- Accuracy of academic and identity records
- Category and reservation certificate validity
Round 3: Technical interview
A 30-45 minute panel interview with senior engineers tests depth in the candidate's discipline and understanding of hydro power generation and project execution. Interviewers may also explore how the candidate would handle site-specific engineering challenges.
- Explaining a core concept relevant to dam construction or turbine operation
- Approach to managing engineering challenges at remote project sites
Round 4: HR and personality round
A 20-30 minute discussion assesses communication, adaptability, and willingness to work at project locations across different states. HR also discusses posting policy, compensation, and allowances for remote assignments.
- Reasons for wanting to join a hydro power PSU
- Handling long postings at remote or hilly project sites
