Experience 1: Executive Trainee (Mechanical) – Selected ✅
Section titled “Experience 1: Executive Trainee (Mechanical) – Selected ✅”Date: October 2024 · Branch: Mechanical · Package: ₹7.2–12 LPA
Written Test
Section titled “Written Test”Technical had thermodynamics, heat transfer, fluid mechanics, and power plant engineering (boiler, turbine, Rankine cycle). A few questions on manufacturing and machine design. Aptitude had quant, reasoning, and verbal. I attempted technical first; negative marking meant I avoided blind guesses. Tip: Power generation and thermal systems are central; revise power plant engineering thoroughly.
Technical Round
Section titled “Technical Round”Started with “Introduce yourself” and project discussion. Then: explain Rankine cycle with T-s diagram, types of boilers, difference between impulse and reaction turbine, and heat transfer in condensers. They asked why NTPC and if I’m willing to work at plant locations. Tip: Prepare “Why NTPC?” and show interest in power generation and operations.
HR Round
Section titled “HR Round”Questions: Why NTPC? Interest in power generation? Where do you see yourself in 5 years? Willingness to work at power plants (sometimes remote sites)? Tip: Be clear on relocation; NTPC values commitment to the power sector.
Experience 2: ET (Electrical) – Selected ✅
Section titled “Experience 2: ET (Electrical) – Selected ✅”Date: November 2024 · Branch: Electrical · Package: ₹7.2–12 LPA
Written Test
Section titled “Written Test”Technical covered power systems, electrical machines, power electronics, transmission and distribution, and protection. A few questions on grid and renewable integration. Aptitude was moderate. Tip: Practice NTPC previous year papers; time management and accuracy matter with negative marking.
Technical Round
Section titled “Technical Round”Project discussion, then: explain slip in induction motor, power factor improvement, protection schemes (overcurrent, differential), and basics of grid operation. They asked about my interest in thermal/hydro power. Tip: Link your project to power systems or industrial applications if possible.
HR Round
Section titled “HR Round”Short: family background, why NTPC, knowledge of NTPC’s role (thermal, hydro, renewable), willingness to join as ET. Tip: Research NTPC’s capacity, plants, and recent initiatives (renewable, digital).
