I was interviewed before Feb 2024.
Key quality parameters in cement production include fineness, strength, setting time, and soundness.
Fineness: Determines the particle size of the cement, affecting its strength and setting time.
Strength: Indicates the compressive strength of the cement, crucial for construction durability.
Setting Time: Refers to the time taken for the cement to set and harden, impacting construction timelines.
Soundness: Measures the ab...

Cement testing in a lab involves various tests to ensure quality and performance.
Types of tests include compressive strength, setting time, soundness, and fineness.
Equipment used may include a Vicat apparatus, Le Chatelier apparatus, and sieves.
ASTM and EN standards are commonly followed for cement testing.
Proper sample preparation and testing procedures are crucial for accurate results.
There are typically three layers of cement used in construction projects.
There are three main layers of cement used in construction: the base layer, the screed layer, and the finishing layer.
The base layer is the thickest layer and provides a solid foundation for the structure.
The screed layer is a thinner layer used to level the surface and provide a smooth finish.
The finishing layer is the final layer applied for aes...

I applied via LinkedIn and was interviewed before Dec 2023. There was 1 interview round.
Power distribution is the process of delivering electricity from power plants to consumers through a network of transmission and distribution lines.
Electricity is generated at power plants using various sources such as coal, natural gas, nuclear, or renewable energy.
The electricity is then transmitted at high voltages over long distances through transmission lines to substations.
At substations, the voltage is reduced a...
Different types of sources of electricity include fossil fuels, nuclear power, renewable energy sources, and batteries.
Fossil fuels (coal, oil, natural gas)
Nuclear power
Renewable energy sources (solar, wind, hydro, geothermal)
Batteries (lithium-ion, lead-acid)

Yield is the measure of the amount of usable product obtained from a process or reaction.
Yield is calculated as the ratio of the actual output to the theoretical maximum output.
It is an important metric in manufacturing and production to assess efficiency.
High yield indicates that a process is effective and efficient, while low yield may indicate issues or inefficiencies.
For example, in a chemical reaction, the yield i...
FM stands for Frequency Modulation. In the given context, 2.6 and 2.8 likely refer to specific frequencies.
FM is a method of encoding information on a carrier wave by varying the frequency of the wave.
In the context of 2.6 and 2.8, they could be referring to specific frequencies used in a communication system or equipment.
For example, 2.6 GHz and 2.8 GHz could be frequencies used for wireless communication.

The induction motor starting principle is based on the creation of a rotating magnetic field.
An induction motor starts by applying a voltage to the stator windings, creating a rotating magnetic field.
The rotating magnetic field induces currents in the rotor windings, which in turn creates a magnetic field.
The interaction between the stator and rotor magnetic fields causes the rotor to start rotating.
Different methods l...
Transformer parts include core, windings, insulation, and cooling system.
The core is made of laminated iron or steel and provides a path for magnetic flux.
Windings consist of primary and secondary coils, which are insulated copper wires.
Insulation materials like paper, varnish, or oil are used to insulate the windings.
Cooling systems such as fans, radiators, or oil pumps are used to dissipate heat.
Other parts include b
Over current protection, differential protection, and earth fault protection are methods used to safeguard electrical systems.
Over current protection is used to detect and interrupt excessive current flow in a circuit.
Differential protection compares the current entering and leaving a component to detect faults.
Earth fault protection detects current leakage to the earth and isolates the faulty circuit.
Over current prot...
Cable construction involves multiple layers for insulation and protection.
Cables are typically constructed with multiple layers for insulation and protection.
The innermost layer is the conductor, usually made of copper or aluminum.
The next layer is the insulation, which can be made of materials like PVC, polyethylene, or rubber.
Additional layers may include shielding to protect against electromagnetic interference.
The ...
