Round duration - 100 minutes
Round difficulty - Hard
The test had 3 parts:
1. Aptitude - 20 questions to be done in 25 minutes. (Medium level)
2. Technical MCQs - 25 questions to be done in 35 minutes. (Medium-Hard level) (HTML, JS, CSS, SQL)

Count the total number of set bits in the binary representation of numbers from 1 to N modulo 1e9+7.
Iterate through numbers from 1 to N and count the set bits in their binary representation
Use bitwise operations to count the set bits efficiently
Return the count modulo 1e9+7 for each test case
Given a positive integer 'N', find and return the smallest number 'M', such that the product of all the digits in 'M' is equal to 'N'. If such an 'M' is not possib...
Find the smallest number whose digits multiply to a given number N.
Iterate through possible digits to form the smallest number with product equal to N

Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
Understand the Merge Sort algorithm which involves dividing the array into two halves, sorting each half, and then merging them back together.
Recursively apply the Merge Sort algorithm until the size of each array is 1.
Merge the sorted halves to produce the final sorted array.
Ensure to handle the input constraints such as the number of...

Round difficulty - Medium
This was a managerial cum technical round. I was asked to introduce myself (both technical details and hobbies). Then I was asked about my internship experiences and what I learnt from them. After that, he asked me questions about the projects mentioned in my resume. He tested my in-depth knowledge of the technologies that I used. He also asked me about the alternative solutions and the drawbacks of my solution.
After that, he asked me to speak about Operating Systems for 5 minutes without giving a pause. Then he asked me to speak about the OSI model and the TCP/IP model for the next 5-10 minutes again without giving a pause. He appreciated my perfomance and gave me a coding question.
What is User-defined function? What are its various types in SQL. What is an Alias in SQL?
Then he asked me whether I had any questions.
Given a singly linked list of integers, your task is to implement a function that returns the index/position of an integer value 'N' if it exists in the linked list. Return -1 i...
Implement a function to find the index of a given integer in a singly linked list.
Traverse the linked list while keeping track of the index of each element.
Compare each element with the target integer 'N'.
Return the index if the element is found, otherwise return -1.
Handle cases where the target integer is not found in the linked list.
Round duration - 15 minutes
Round difficulty - Easy
Typical HR questions were asked in this round.
Tip 1 : Revise data structures and operating systems very well.
Tip 2 : Have a good resume with self-made projects and internship experiences as they add value to the candidature.
Tip 3 : Be confident and know the basics well.
Tip 1 : Have some good projects and know the tech stack well enough.
Tip 2 : Never include anything which you are not confident about.
Top trending discussions
Switch case is used for multiple conditions while if else is for binary conditions. Sorting can be done using various algorithms.
Switch case is faster than if else for multiple conditions
If else is more readable for binary conditions
Sorting can be done using bubble sort, insertion sort, quick sort, etc.
Example code for bubble sort: for(i=0;i
Difference between compiler and interpreter with a coding challenge
Compiler translates the entire code into machine language before execution while interpreter translates line by line during execution
Compiler generates an executable file while interpreter does not
Compiler is faster but debugging is harder while interpreter is slower but debugging is easier
Coding challenge: Write a program to find the sum of two numbers

Agile methodologies
OOPs concepts in Java include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods together in a class.
Inheritance: Creating new classes from existing ones, inheriting their properties and behaviors.
Polymorphism: Objects of different classes can be treated as objects of a common superclass.
Abstraction: Hiding complex implementation details and providing a simplified interfa
Abstraction can be achieved through interfaces, abstract classes, and encapsulation.
Using interfaces to define a set of methods that a class must implement
Using abstract classes to provide a base implementation that can be extended by subclasses
Encapsulating implementation details to hide complexity and provide a simpler interface
Using design patterns such as Factory and Strategy to abstract away implementation details
Class is a blueprint for creating objects while interface defines a contract for implementing classes.
Class is a template for creating objects with properties and methods.
Interface is a contract that defines a set of methods and properties that a class must implement.
Object is an instance of a class that has its own set of properties and methods.
Function instance is a reference to a function that can be called with arg...
Access modifiers control the visibility and accessibility of class members.
Access modifiers include public, private, protected, and internal.
Public members can be accessed from anywhere.
Private members can only be accessed within the same class.
Protected members can be accessed within the same class and its subclasses.
Internal members can be accessed within the same assembly.
Access modifiers help enforce encapsulation ...
Cloud refers to the delivery of computing services over the internet.
Cloud computing allows users to access data and applications from anywhere with an internet connection.
Cloud services can be categorized into three main types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
Cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

There are multiple ways to achieve tasks on AWS depending on the specific task.
Using AWS Management Console
Using AWS CLI
Using AWS SDKs
Using AWS CloudFormation
Using AWS Elastic Beanstalk
Using AWS Lambda
Using AWS Step Functions
Using AWS Batch

SID stands for Security Identifier. It is a unique identifier assigned to a user, group, or computer account in Windows.
SID is used to control access to resources in Windows
It is a string of alphanumeric characters
SID is generated by the Windows operating system during the creation of an account
It is used to identify users, groups, and computers in a network
