National Aluminium Company Limited (NALCO) is a Schedule ‘A’ Navratna CPSE established on 7th January, 1981 having its registered office at Bhubaneswar. It is one of the largest integrated Bauxite-Alumina-Aluminium- Power Complex in the Country. At present, Government of India holds 51.28% of paid-up equity capital. The Company has been operating its captive Panchpatmali Bauxite Mines for the pit head Alumina refinery at Damanjodi, in the District of Koraput in Odisha and Aluminium Smelter & Captive Power Plant at Angul. As a part of green initiative, NALCO has installed 198 MW Wind Power Plants at various locations in India and 850 kWp roof top Solar Power Plants at its premises to join hands for carbon neutrality. From the days of first commercial operation since 1987 the Company has continuously earned profits for last 36 years. NALCO is one of the leading foreign exchange earning CPSEs of the Country. The Company continues to retain its position of lowest cost producer in Bauxite and Alumina production in the World in 2022.
The Company, while climbing the ladder of success has strived hard to play a significant role in the socio-economic development in its operational areas through empathetic CSR activities. Rehabilitation of displaced families, employment, income generation, health care and sanitation of local people, education & skill development, providing safe drinking water, development of infrastructure, pollution control, environmental measures, rural development, promotion of arts, crafts, & culture, and various humanitarian goodwill missions have earned NALCO a place of pride in the corporate world.
NALCO has recently released a list of 2086 shortlisted candidates for the posts of 277 Graduate Engineer Trainees in various departments and disciplines, out of these, 670 candidates are shortlisted for 100 posts of Graduate Engineer Trainees (Electrical) at NALCO. As one of the leading PSUs in India, NALCO provides a wide range of opportunities for candidates looking for a challenging and rewarding career.

NALCO Interview Strategy
Many students ask this question. Students think that reading some different books will help them developing the concepts being asked in the NALCO interview. Actually, it is not true. Concepts learned from any book will be sufficient if you have done them properly. Questions asked will be simple but require thinking. So, the best way to learn to swim is to start swimming. Similarly, best way to master the art of interviews is to start facing them. Start going for the mock interviews of NALCO for the Posts of Graduate Engineer Trainees (Electrical). will focus on assessing your knowledge, skills, and suitability for the specific post. There will be HR & technical rounds. Here are some sample questions to give you an idea:
• Introduce yourself.
• How do you prioritize tasks when faced with multiple deadlines in a project?
• Give an example of a time when you had to make a quick decision in a challenging situation. What was the outcome?
• Describe a situation where you had to work as part of a team to achieve a common goal.
• What are the differences between AC (alternating current) and DC (direct current) circuits?
• Describe the concept of electric power and its units of measurement.
• How would you analyze a series and parallel circuit?
• Discuss the principles of voltage, current, and resistance in electrical circuits.
• Explain the significance of Kirchhoff's laws in circuit analysis.
• Describe the operating principles of transformers.
• How would you determine the efficiency of an electric motor?
• Discuss the differences between synchronous and asynchronous (induction) motors.
• What are the components of a power distribution system?
• How would you analyze and mitigate power factor issues in an electrical network?
• Explain the concept of load flow analysis in power systems.
• Describe the components and working principles of a feedback control system.
• How would you design a PID (Proportional-Integral-Derivative) controller for a temperature control system?
• Discuss the applications of PLCs (Programmable Logic Controllers) in industrial automation.
• Explain the operation of diodes and transistors.
• What are the differences between BJT (Bipolar Junction Transistor) and MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor)?
• Discuss the applications of operational amplifiers (op-amps) in electronic circuits.
• How does a photovoltaic (solar) system convert sunlight into electricity?
• Discuss the role of inverters in renewable energy systems.
• What are the challenges and advantages of integrating renewable energy sources into the power grid?
• What are the key safety considerations when working with electrical systems?
• How would you ensure compliance with electrical standards (e.g., NEC, IEC)?
• Describe the importance of grounding and bonding in electrical installations.
• Explain the basic principles of digital logic circuits (e.g., AND, OR, NOT gates).
• How would you program a microcontroller for a specific application?
• Discuss the advantages of using FPGA (Field-Programmable Gate Array) in digital design.
• Discuss current trends in electrical engineering (e.g., IoT, smart grids, electric vehicles).
• How are advancements in battery technology impacting the field of electrical engineering?
• What role does sustainability play in the design and implementation of electrical systems?
