I was interviewed in Dec 2024.
A torque converter is a fluid coupling that transfers power from the engine to the transmission in an automatic vehicle.
It allows the engine to keep running while the vehicle is stopped
It multiplies torque to increase power output
Consists of three main components: impeller, turbine, and stator
Commonly found in automatic transmission vehicles
Transmission works by transferring power from the engine to the wheels, allowing the vehicle to change speed and direction.
Transmission uses gears to control the power flow from the engine to the wheels
The driver selects the appropriate gear based on speed and terrain
Automatic transmissions use a torque converter to transfer power smoothly
Manual transmissions require the driver to engage and disengage gears using a clu...
There are mainly three types of differentials: open differential, limited-slip differential, and locking differential.
Open differential allows wheels to spin at different speeds, useful for regular driving conditions.
Limited-slip differential limits the speed difference between wheels, providing better traction.
Locking differential locks both wheels together, ensuring equal power distribution for maximum traction.
There are mainly two types of hydraulic pumps: gear pumps and piston pumps.
Gear pumps: simple design, cost-effective, suitable for low to medium pressure applications
Piston pumps: higher efficiency, suitable for high pressure applications, more complex design
Other types include vane pumps, radial piston pumps, and axial piston pumps
To check if a potentiometer is working properly, you can use a multimeter to measure the resistance across its terminals.
Set the multimeter to the resistance measurement mode.
Connect the multimeter leads to the outer two terminals of the potentiometer.
Slowly turn the potentiometer knob and observe the resistance value on the multimeter.
The resistance should change smoothly and continuously as you turn the knob.
If the r...

The duration was 50 minutes and included 55 questions focused on technical areas related to mechanical, electrical, and hydraulic systems, as well as some questions on safety and reasoning.
I applied via LinkedIn
I applied via Company Website and was interviewed in Nov 2024. There were 2 interview rounds.
I applied via Recruitment Consulltant and was interviewed in Oct 2024. There was 1 interview round.
I would first check the battery, then the starter motor, and finally the ignition system.
Check the battery for charge and connections
Inspect the starter motor for any issues
Test the ignition system for spark
Check for any loose wires or connections
Gear pump and displacement pump are types of positive displacement pumps used to move fluids by trapping a fixed amount of fluid and forcing it through the pump.
Gear pump uses rotating gears to move fluid, while displacement pump moves fluid by changing the volume of a chamber.
Gear pump is more compact and efficient, while displacement pump is more accurate and suitable for high pressure applications.
Examples of gear p...

I was interviewed in Mar 2024.
Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge pipe. Negative displacement pumps move fluid by creating a vacuum to draw in and push out the fluid.
Positive displacement pumps trap a fixed amount of fluid and force it through the discharge pipe
Examples include gear pumps, piston pumps, and diaphragm pumps
Negative displacement pumps create a vacuum to draw in and pu...
The material used for casing is typically chosen based on factors such as durability, weight, cost, and aesthetics.
Common materials for casing include plastic, aluminum, steel, and carbon fiber.
Plastic is often used for its lightweight properties and cost-effectiveness.
Aluminum is chosen for its strength-to-weight ratio and corrosion resistance.
Steel is preferred for its durability and impact resistance.
Carbon fiber is...
I applied via Campus Placement and was interviewed in Jan 2024. There was 1 interview round.
Friction is the force resisting the relative motion of solid surfaces, gears are of various types like spur, helical, bevel, etc., stress is the force applied to a material, strain is the deformation caused by stress.
Friction is the force that opposes the motion of one surface over another.
Types of gears include spur gears, helical gears, bevel gears, worm gears, etc.
Stress is the force applied to a material per unit a...
Common materials for shafts include steel, stainless steel, aluminum, and titanium.
Steel is a popular choice for its strength and durability
Stainless steel is corrosion resistant
Aluminum is lightweight and has good thermal conductivity
Titanium is strong and lightweight, often used in aerospace applications
I applied via LinkedIn and was interviewed in Aug 2023. There were 3 interview rounds.
There are various types of pumps used in different industries such as centrifugal, positive displacement, and axial flow pumps.
Centrifugal pumps are commonly used in water treatment, chemical processing, and HVAC systems.
Positive displacement pumps are used in food processing, oil and gas, and pharmaceutical industries.
Axial flow pumps are used in irrigation, flood control, and water supply systems.
Other types of pumps...
The most common problem in hydraulic systems is fluid contamination.
Fluid contamination
Leakage in hoses and fittings
Cavitation
Overheating
Wear and tear of components
CAN bus system is a communication protocol used in vehicles to allow microcontrollers and devices to communicate with each other.
CAN stands for Controller Area Network
It is a two-wire communication system
It allows for real-time data transmission between devices
It is commonly used in automotive and industrial applications
Examples of devices that use CAN bus include engine control units, airbag systems, and anti-lock bra
