I applied via Referral and was interviewed before Dec 2022. There were 3 interview rounds.
Well it was my basic introduction and hobbies and stuff
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor that is widely used in electronic devices.
MOSFET is a three-terminal device that can amplify or switch electronic signals.
It is made up of a metal gate electrode, an insulating layer of oxide, and a semiconductor channel.
MOSFETs are commonly used in integrated circuits (ICs) and power electronics.
They are used in various applications s...
The voltage divider circuit is used to divide a voltage into smaller fractions using resistors.
The output voltage can be calculated using the formula Vout = Vin * (R2 / (R1 + R2))
The resistors R1 and R2 are connected in series between the input voltage source and ground
The voltage across R2 is the output voltage Vout
The voltage across R1 is Vin - Vout
The ratio of R2 to the total resistance (R1 + R2) determines the outp
A multimeter is a versatile tool used to measure electrical quantities such as voltage, current, and resistance.
Start by selecting the appropriate measurement function on the multimeter (e.g., voltage, current, resistance).
Ensure the multimeter is set to the correct range for the expected value.
Connect the test leads to the appropriate terminals on the multimeter.
Place the test leads across the component or circuit bei...
An induction motor is an AC electric motor in which power is supplied to the rotor by electromagnetic induction.
An induction motor is commonly used in various applications such as industrial machinery, household appliances, and electric vehicles.
It operates on the principle of electromagnetic induction, where a rotating magnetic field is created by the stator winding.
The rotating magnetic field induces currents in the ...
VFDs, or Variable Frequency Drives, are electronic devices used to control the speed and torque of electric motors.
VFDs are commonly used in industrial applications to regulate the speed of motors in machinery.
They work by adjusting the frequency and voltage supplied to the motor, allowing for precise control over its speed and torque.
VFDs can help save energy by reducing the motor's speed when full power is not requir...
EMI EMC test refers to electromagnetic interference and electromagnetic compatibility testing.
EMI EMC test is conducted to assess the ability of electronic devices to function properly in the presence of electromagnetic interference.
It involves measuring the electromagnetic emissions from the device under test and ensuring that they comply with regulatory standards.
EMC testing is performed to ensure that electronic dev...

Valve design calculation involves determining the valve size, type, and material based on the fluid properties and system requirements.
Determine the flow rate and pressure drop across the valve
Select the appropriate valve type (e.g. globe, gate, ball) based on the application
Choose the valve material based on the fluid properties and compatibility
Calculate the valve size based on the flow rate and pressure drop
Consider...

The difference between == and === is that == compares the values of two variables, while === compares both the values and the data types.
The == operator performs type coercion, meaning it converts the operands to a common type before comparison.
The === operator does not perform type coercion and requires both the values and the data types to be the same for a true comparison.
For example, 1 == '1' returns true because t...
MCB is a miniature circuit breaker used for low currents, while MCCB is a molded case circuit breaker used for higher currents.
MCB is designed for low currents, typically up to 100A, while MCCB is designed for higher currents, typically up to 2500A.
MCB is a compact device with fixed trip settings, while MCCB is larger and has adjustable trip settings.
MCB is commonly used in residential and commercial applications, whil...
A relay is an electrically operated switch that uses an electromagnet to mechanically operate the switch contacts.
Relays are used to control high power circuits with a low power signal.
When the coil of the relay is energized, it creates a magnetic field that causes the switch contacts to close or open.
Relays are commonly used in automotive applications, industrial controls, and home appliances.
There are different types...
