I applied via campus placement at National Institute of Technology (NIT), Rourkela and was interviewed before Nov 2023. There was 1 interview round.
SPI (Serial Peripheral Interface) is a synchronous serial communication protocol commonly used in embedded systems.
SPI is a full-duplex communication protocol, meaning data can be sent and received simultaneously.
It uses four wires for communication: MISO (Master In Slave Out), MOSI (Master Out Slave In), SCK (Serial Clock), and SS (Slave Select).
SPI devices are typically classified as master or slave, with the master ...
A microcontroller is a compact integrated circuit designed to perform specific tasks, while a processor is a general-purpose device used for executing instructions.
Microcontrollers typically have built-in memory and peripherals, while processors require external components for operation.
Microcontrollers are commonly used in embedded systems like IoT devices and consumer electronics, while processors are found in comput...
Multiplexing in digital domain involves combining multiple signals into one signal for transmission over a single channel.
Multiplexing allows for efficient use of bandwidth by combining multiple signals into one
Types of multiplexing include time-division multiplexing (TDM) and frequency-division multiplexing (FDM)
Example: TDM divides time into slots for each signal to transmit data sequentially

Motors are rated in KW because they consume power, while transformers and generators are rated in KVA because they produce power.
Motors convert electrical energy into mechanical energy, so they consume power and are rated in KW.
Transformers and generators produce electrical energy, so they are rated in KVA based on their apparent power.
KVA takes into account both the real power (KW) and the reactive power (KVAR) produc...
The type of motor used in ceiling fans is an induction motor.
Ceiling fans typically use single-phase induction motors.
These motors are designed to provide a constant speed and are efficient in converting electrical energy into mechanical energy.
The motor consists of a stator and a rotor, with the stator being the stationary part and the rotor being the rotating part.
The stator contains windings that create a rotating m...
A thermal power plant generates electricity by converting heat energy into mechanical energy.
Thermal power plants use fossil fuels or nuclear energy to heat water and produce steam.
The steam drives a turbine, which is connected to a generator that produces electricity.
The heat source can be coal, natural gas, oil, or nuclear reactions.
The steam is condensed back into water and recycled in a closed-loop system.
Thermal p...
A program to generate a geometric progression (GP).
Take the first term, common ratio and number of terms as input.
Use a loop to calculate each term of the GP.
Print the generated GP as output.
A program to print factorial using recursion
Define a function to calculate factorial recursively
Base case: if the number is 0 or 1, return 1
Recursive case: multiply the number with factorial of (number - 1)
Print the factorial of a given number
Logic to reverse a string without using string functions
Iterate through the string from the last character to the first
Create a new string and append each character to it in reverse order
Caching is the process of storing frequently used data in a temporary storage to reduce access time. LRU caching removes least recently used data.
Caching improves performance by reducing access time to frequently used data
LRU (Least Recently Used) caching removes the least recently used data to make space for new data
LRU cache can be implemented using a doubly linked list and a hash map
When a cache hit occurs, the acce...
No, I am not a loner.
I enjoy working in a team and collaborating with others.
I believe that teamwork leads to better results.
I am comfortable working with people from diverse backgrounds.
I actively seek out opportunities to network and build relationships.
I am a good listener and value the opinions of others.
