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

Timing: Morning
How was the environment? It happened in the Computer Lab of my institution
All students were assigned a computer and we had to solve questions on hackerrank
Consider 'N' individuals numbered from 0 to N-1 standing in a queue. You are provided with two arrays: Height
and Infront
, each consisting of 'N' non-negative int...
The task is to find the actual order of people in a queue based on their heights and the number of taller people in front of them.
Iterate through the given arrays and create a list of tuples containing the height and number of taller people for each person.
Sort the list of tuples in descending order of height and ascending order of the number of taller people.
Create an empty result list and insert each tuple into the r...

Round was a mix of concepts from OOPS, OS and Problem Solving
Given a Binary Search Tree (BST) and a key value 'X', determine if there exists a node within the BST containing the value 'X'.
Consider the tree represe...
The task is to find if a given value is present in a Binary Search Tree (BST).
Start from the root node and compare the value with the target value.
If the value matches, return true.
If the target value is less than the current node value, move to the left child.
If the target value is greater than the current node value, move to the right child.
Repeat the process until a match is found or a leaf node is reached.
If a leaf...
Tip 1 : Try to code the data structures that you have learned to understand things better
Tip 2 : Try to solve the problem even if it is the worst possible solution you think and then try to optimize don't jump to get the
best possible solution
Tip 3 : Discuss things among peers it helps to improve the understanding, even try to teach someone anything new you learn, this is very helpful during the interviews as you will have habit of explaining things
Tip 1 : Try to be honest in the resume don't write something you don't know, most of the time it backfires.
Tip 2 : Try to make 2 good projects for cv and know about the challenges you can face on the project and think about how you can solve that challenge.
I was interviewed before Sep 2020.

Its a zoom call interview which lasted for 45 minutes. initially there are two panel members in which one is very targetting at me. They asked me different type of questions like jumping from DSA to project then to python then again java. Its a mixed combo pack type interview. for each and every question they asked me the real time example. The discussion on my project lasted for 15-20 mins.
Given a positive integer N
, compute the total number of '1's in the binary representation of all numbers from 1 to N. Return this count modulo 1e9+7 because the result can...
Count the total number of set bits in the binary representation of numbers from 1 to N modulo 1e9+7.
Use bitwise operations to count the set bits in each number from 1 to N.
Keep track of the total set bits and return the result modulo 1e9+7.
Optimize the solution to handle large values of N efficiently.
Consider using dynamic programming or precomputing values for faster computation.

This round was a zoom interview. The interview started with my brief introduction. This time the interview was more interested in my hobbies and passions. He asked me what do you do to keep yourself updated with the latest technology trends?
Tip 1 : Do participate in all the coding contests, long challenges held by codechef, codeforces
Tip 2 : Practice all kinds of problems on leetcode, gfg, coding ninjas
Tip 3 : When you are writing a written exam for a particular company, make sure you get to know about the company in detail.
Tip 1 : Make your resume short and sweet(mostly 1 page, max 2 pages) is preferred.
Tip 2 : Make sure your resume is crisp rather than descriptive
Tip 3 : Do not lie on your resume
