The National Hydroelectric Power Corporation syllabus

The National Hydroelectric Power Corporation (NHPC) Junior Engineer (JE) selection process for 2025 is based on a Computer Based Test (CBT). The syllabus is divided into three main parts: the candidate’s Specific Engineering Discipline, General Awareness, and Reasoning Ability.

The exam pattern is generally structured as follows:

Part	Subject	Questions	Marks
I	Specific Discipline (Civil/Electrical/Mechanical/E&C)	140	140
II	General Awareness	30	30
III	Reasoning Ability	30	30
Total		200	200

• Duration: 3 Hours (180 Minutes)
• Marking: +1 for each correct answer.
• Negative Marking: -0.25 (1/4th) mark deduction for each wrong answer.
