I applied via Recruitment Consulltant and was interviewed before Jan 2023. There were 2 interview rounds.
CBM stands for Condition-Based Maintenance and TBM stands for Tunnel Boring Machine.
CBM is a maintenance strategy that uses real-time data to determine the condition of equipment and schedule maintenance accordingly.
TBM is a machine used to excavate tunnels with a circular cross-section through a variety of soil and rock strata.
MTTR (Mean Time to Repair) is the average time required to repair a failed component or syst...
A hydraulic system is a technology that uses fluid to transmit power and control movement.
Hydraulic systems use a fluid, typically oil or water, to transmit power.
The system consists of a pump, valves, actuators, and fluid lines.
The pump pressurizes the fluid, which is then distributed through the system.
Valves control the flow and direction of the fluid.
Actuators, such as cylinders or motors, convert the fluid pressur...

I applied via Approached by Company and was interviewed in Sep 2022. There were 2 interview rounds.
The heat generating component in a motor is the stator winding and rotor core.
Stator winding and rotor core are the main sources of heat generation in a motor.
The heat generated is due to the resistance of the winding and core losses.
Efficient cooling systems are required to dissipate the heat and prevent damage to the motor.
Examples of cooling systems include air cooling, liquid cooling, and forced ventilation.
Cooling methods for motors include air cooling, liquid cooling, and oil cooling.
Air cooling involves using a fan to circulate air over the motor to dissipate heat.
Liquid cooling uses a coolant, such as water or a mixture of water and glycol, to absorb heat from the motor and transfer it to a radiator.
Oil cooling involves circulating oil through the motor to absorb heat and then transferring it to a heat exchanger.
The c...

A lathe machine is classified based on its size, design, and functionality.
Classification based on size: mini lathe, bench lathe, engine lathe, turret lathe, etc.
Classification based on design: horizontal lathe, vertical lathe, center lathe, etc.
Classification based on functionality: CNC lathe, manual lathe, automatic lathe, etc.
I applied via Approached by Company and was interviewed in Aug 2022. There were 2 interview rounds.
Drive cycle refers to the pattern of vehicle operation over a specified period of time.
Drive cycle is used to evaluate vehicle emissions and fuel economy.
It includes different driving modes such as idling, acceleration, deceleration, and cruising.
Examples of drive cycles include FTP-75, HWFET, and US06.
Drive cycle data is used to develop and test new vehicle technologies.
Drive cycles can vary depending on the type of v
The major heating components in an EV motor are the stator winding and the rotor.
Stator winding: The stator winding is responsible for generating a rotating magnetic field in the motor. It can experience heating due to electrical resistance.
Rotor: The rotor is the rotating part of the motor and can also generate heat due to friction and electrical resistance.
Cooling system: EV motors often have a cooling system to diss...

I was interviewed before Feb 2024.
Different types of hardness include scratch hardness, indentation hardness, and rebound hardness.
Scratch hardness is the resistance of a material to scratching or abrasion.
Indentation hardness is the resistance of a material to permanent deformation caused by a constant load.
Rebound hardness is the ability of a material to absorb energy and return it upon impact.
Examples include Mohs scale for scratch hardness, Rockwel...
The full form of HRC scale is Rockwell Hardness Scale C.
HRC stands for Rockwell Hardness Scale C.
It is a measure of the hardness of a material, commonly used in metallurgy.
The HRC scale is often used to determine the hardness of steel.
Higher HRC values indicate harder materials.
