- Q1. Why UDP and not TCP in project
- Ans.
UDP is preferred over TCP in this project due to its low latency and lightweight nature.
UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.
UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.
UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...
- Q2. How would you clear the 7th bit in a 32 bit register
- Ans.
To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.
Create a mask with the 7th bit set to 0 and all other bits set to 1
Perform a bitwise AND operation between the register and the mask
Store the result back in the register
Interview Preparation Tips
Experience: Questions were based on C concepts, given piece of code, find error, output, etc then data structures, bit manipulation, a few aptitude questions were also there (around 5-7).
Tips: Practice aptitude, C, data structures (geeksforgeeks.org is a good source).
Duration: 1 hour
Total Questions: 30
Round: Technical + HR Interview
Experience: I was asked to explain project in detail, I had done projects on embedded, so was asked about that, details like what fields did you use in that structure, why this implementation and not some related other. Memory management, network communications, operating systems. Then questions on C concepts like memory allocation, function pointers, then data structures like linked lists, then bit manipulation in registers. Questions from electrical coursework. Then later, why higher studies, would you still go for higher studies if you had a good job at a company, why etc.
Tips: Be thorough with C (know your Kernighan & Ritchie) and be prepared to go into details about your projects.

Interview Preparation Tips
Experience: questions were mainly asked on C, data structures linked lists, wireless communications. i was asked questions on pointers, linked lists, difference between structures and unions, endien-ness(big or little)
about microprocesors- interrupt scheme: which scheme is better , when?
about assembly programming.
They may ask you to write assembly codes/C program
emphasis is on the logic used and not so much on the syntax.
Tips: do C really well. they ask you about projects. also do communication subjects, microprocessors.
they prefer if you know about data structures and OS but it's okay even if you don't.
be honest. if you don't know something say you don't.
do your final year project well.

Technical Interview round with questions on OOPS and OS mainly.
- Q1. What are Little Endian and Big Endian in the context of computer architecture?
- Ans.
Little Endian and Big Endian refer to the order in which bytes are stored in computer memory.
Little Endian stores the least significant byte first, while Big Endian stores the most significant byte first.
Little Endian is commonly used in x86 architecture, while Big Endian is used in architectures like SPARC and PowerPC.
Endianness can affect data transmission between systems with different byte orders.
- Q2. Write a program to determine if your system is little-endian or big-endian.
- Ans.
Program to determine system's endianness
Check the endianness by storing a multi-byte integer and checking the byte order
Use bitwise operations to extract the least significant byte
If the least significant byte is at the lowest memory address, it's little-endian
If the least significant byte is at the highest memory address, it's big-endian
- Q3. What is the volatile keyword in programming?
- Ans.
The volatile keyword in programming is used to indicate that a variable's value can be changed unexpectedly.
Volatile keyword is used in multithreaded programming to prevent compiler optimizations on variables that can be changed by other threads.
It tells the compiler not to cache the variable's value in a register, ensuring that every access is made to the variable's memory location.
Commonly used in embedded systems pr...
- Q4. What is the use of a function pointer in C?
- Ans.
Function pointers in C are used to store the address of functions, allowing for dynamic function calls and callbacks.
Function pointers can be used to implement callbacks in event-driven programming.
They can be used to switch between different functions at runtime.
Function pointers are commonly used in implementing data structures like function pointers in an array of function pointers.
Example: void (*funcPtr)(int) = &a
- Q5. Design a data structure to implement multi-threading.
- Ans.
Design a data structure for multi-threading
Use a thread-safe queue to manage tasks for each thread
Implement a lock or semaphore to control access to shared resources
Consider using condition variables for synchronization
Use atomic operations for shared variables to prevent race conditions
- Q6. What does a kernel do?
- Ans.
The kernel is the core component of an operating system that manages system resources and provides a bridge between software and hardware.
Manages system resources such as CPU, memory, and I/O devices
Provides a bridge between software applications and hardware components
Handles tasks such as process scheduling, memory management, and device drivers
Controls communication between hardware and software layers
- Q7. What is a storage class in programming?
- Ans.
A storage class in programming defines the scope and lifetime of variables.
Storage classes include auto, register, static, and extern.
Auto variables are created when a function is called and destroyed when the function ends.
Register variables are stored in CPU registers for faster access.
Static variables retain their value between function calls.
Extern variables are declared outside of any function and can be accessed
