First round is online test of 3 virtual rounds consist of aptitude , and coding
A singly linked list is a data structure where each element points to the next element in the list.
Each node in the list contains data and a reference to the next node
Traversal starts from the head node and follows the next pointers until the end
Insertion and deletion can be done efficiently at the beginning or end of the list
It is easy and you can clear it.
It was moderate and hard questions

I was interviewed in Sep 2017.
An SR flip-flop can be implemented using NAND gates.
Use two NAND gates to create the SR flip-flop.
Connect the output of one NAND gate to the input of the other NAND gate.
Connect the Set (S) and Reset (R) inputs to the inputs of the NAND gates.
The output of the first NAND gate is the Q output, and the output of the second NAND gate is the Q̅ output.
The answer describes the steps to find and display the temperature of N rooms.
Create an array to store the temperature of each room
Iterate through each room and prompt the user to enter the temperature
Store the temperature in the corresponding array index
Display the temperature of each room

I was interviewed in Sep 2016.
I applied via Campus Placement
A program is a set of instructions that tells a computer what to do. A task is a unit of work performed by a program. A thread is a sequence of instructions within a task.
A program is a collection of instructions that are executed by a computer to perform a specific task.
A task is a unit of work that is performed by a program. It can be a specific action or a set of actions.
A thread is a sequence of instructions within...
To delete a node in a linked list, we need to adjust the pointers of the previous and next nodes.
Find the node to be deleted by traversing the linked list
Adjust the pointers of the previous and next nodes to skip the node to be deleted
Free the memory occupied by the node to be deleted
A function pointer is a variable that stores the address of a function. Volatile type is used to declare variables that can be modified by external factors.
Function pointers are used to pass functions as arguments to other functions.
Volatile type is used when a variable's value can be changed unexpectedly by external factors.
Function pointers can be used to implement callbacks or event handling mechanisms.
Volatile type...

Round duration - 60 minutes
Round difficulty - Easy
Technical Interview round with questions on OOPS and OS mainly.
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.
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
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...
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
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
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
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
Round duration - 30 minutes
Round difficulty - Easy

malloc is a function in C programming used to dynamically allocate memory during runtime.
malloc stands for 'memory allocation'.
It is used to allocate a specific amount of memory during program execution.
The allocated memory is not automatically initialized and must be explicitly freed using the free() function to avoid memory leaks.
