I applied via Referral and was interviewed before Jul 2023. There were 2 interview rounds.
Concrete grades are classifications that indicate the strength of the concrete mix used in construction.
Concrete grades are denoted by the letter 'M' followed by a number, such as M20, M30, etc.
The number after 'M' represents the compressive strength of concrete in N/mm^2 after 28 days of curing.
Higher grade numbers indicate higher strength concrete, suitable for different types of construction projects.
For example, M2...
Concrete strength typically reaches about 70-80% of its final strength after 7 days.
Concrete strength gain after 7 days is usually around 70-80% of its final strength
Factors such as mix design, curing conditions, and type of cement can affect the rate of strength gain
For example, high early strength concrete may reach higher percentages of its final strength after 7 days compared to normal concrete
Non destructive testing of concrete is a method used to evaluate the properties of concrete without causing damage.
Methods include ultrasonic testing, rebound hammer, and ground penetrating radar.
These tests help assess the strength, durability, and quality of concrete structures.
Non destructive testing is essential for ensuring the safety and longevity of buildings and infrastructure.
Examples of non destructive testin...
Transportation of concrete involves mixing, loading, and delivering the concrete to the construction site.
Concrete is mixed at a batching plant using cement, sand, gravel, and water.
The mixed concrete is then loaded into transit mixers or concrete trucks for transportation.
Transit mixers rotate to prevent the concrete from setting during transportation.
Concrete pumps can also be used to transport concrete to hard-to-re
Admixtures are used in ready mixed concrete to improve workability, durability, and strength.
Admixtures help in reducing water content while maintaining workability.
They enhance the durability of concrete by reducing permeability and increasing resistance to chemicals.
Admixtures can also accelerate or retard the setting time of concrete.
Examples of admixtures include water reducers, accelerators, retarders, and air-ent
I applied via Naukri.com and was interviewed in Nov 2023. There was 1 interview round.
A 1 gigawatt required pallet is a pallet that can handle the weight and power requirements of a 1 gigawatt load.
A 1 gigawatt required pallet needs to be able to support the weight of a 1 gigawatt load.
It should have a strong and sturdy construction to prevent any damage or collapse.
The pallet should be designed to handle the power requirements of a 1 gigawatt load, ensuring proper electrical connections and insulation.

Blocking diodes are used in junction boxes to prevent reverse current flow and protect electrical components.
Blocking diodes are used to prevent reverse current flow in electrical circuits.
They protect electrical components from damage caused by reverse voltage.
Blocking diodes are commonly used in junction boxes to ensure proper current flow.
They are also used in solar panels to prevent power loss due to reverse curren...
If module temperature increases, it can lead to reduced efficiency, increased stress on components, and potential failure.
Increased temperature can cause a decrease in the efficiency of the module.
Higher temperatures can lead to increased stress on components, potentially reducing their lifespan.
Excessive heat can cause thermal expansion and contraction, which may result in mechanical failure.
Increased temperature can ...

I applied via Company Website and was interviewed in Apr 2023. There were 3 interview rounds.
A sinusoidal wave is a type of wave that has a smooth, repetitive oscillation resembling a sine curve.
Sinusoidal waves are characterized by their amplitude, frequency, and phase.
They are commonly seen in AC electrical circuits, sound waves, and light waves.
The equation for a sinusoidal wave is typically represented as y = A*sin(2*pi*f*t + phi), where A is the amplitude, f is the frequency, t is time, and phi is the pha...
Peak factor is the ratio of peak value to the RMS value of a waveform.
Peak factor is used to quantify the peakiness of a waveform.
It is calculated by dividing the peak value of the waveform by its RMS value.
A higher peak factor indicates a more peaky waveform with larger peaks relative to the average value.
Peak factor is important in signal processing and power systems analysis.
The stator and rotor are key components of an electric motor. The stator is the stationary part that generates a magnetic field, while the rotor is the rotating part that interacts with the magnetic field to produce motion.

I applied via Referral and was interviewed in Mar 2024. There were 2 interview rounds.
Possible reasons for cube failure despite good materials
Improper mixing of materials
Incorrect curing process
Inadequate compaction of concrete
Presence of air voids or impurities
Poor quality control during manufacturing
Compression test is conducted after cube test to determine the compressive strength of concrete.
Compression test is conducted to determine the compressive strength of concrete.
It involves applying a gradually increasing load to the concrete specimen until failure.
The results of the compression test help in assessing the quality of the concrete mix and its ability to withstand compressive forces.
Compression test is an i...
The quantity of cement used in M35 grade concrete varies depending on the mix design and specifications.
The quantity of cement in M35 grade concrete typically ranges from 360 to 420 kg/m3.
The exact amount of cement needed can be calculated using the mix design provided for the project.
Factors such as water-cement ratio, aggregate size, and admixtures also influence the quantity of cement required.
