I applied via Approached by Company and was interviewed in Dec 2021. There were 4 interview rounds.
A power tester is a device used to test the functionality and safety of electrical power systems.
Power testers are used to check voltage levels, continuity, and resistance in electrical circuits.
They are commonly used by electricians, technicians, and engineers in various industries.
Power testers can help identify faulty wiring, circuit breakers, and electrical components.
They ensure compliance with safety standards an...
PCC and RCC grades are used to classify the strength of concrete.
PCC stands for Plain Cement Concrete and is classified into M5, M7.5, M10, M15, M20, M25, M30, M35, M40, M45, M50, M55, M60, and M70 grades based on its compressive strength.
RCC stands for Reinforced Cement Concrete and is classified into M15, M20, M25, M30, M35, M40, M45, M50, M55, M60, and M70 grades based on its compressive strength.
The higher the grad...

Maths question, and reasoning
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.
Energy is conserved in a closed system
Energy can be transferred between different forms (e.g. heat, work)
The total energy of a system remains constant
Mathematically expressed as: ΔU = Q - W, where ΔU is the change in internal energy, Q is heat added to the system, and W is work done by the system
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
Entropy tends to increase in a closed system
Heat energy naturally flows from hot to cold objects
Efficiency of energy conversion processes is limited by the second law

The erection sequence of a continuous casting plant involves several steps. There are two types of casters: vertical and horizontal.
The first step is to install the foundation and anchor bolts.
Next, the columns and beams are erected.
After that, the equipment such as tundish, mold, and rollers are installed.
Finally, the electrical and hydraulic systems are connected.
There are two types of casters: vertical and horizonta...
The casting shop requires utilities such as electricity, compressed air, natural gas, and water of specific quality and type.
Electricity is required for powering the equipment and lighting.
Compressed air is used for cleaning and operating pneumatic tools.
Natural gas is used for heating the furnaces.
Water of specific quality and type is required for cooling and cleaning purposes.
Water quality should be free from impurit...
