A closure is a function that has access to its own scope, as well as the outer function's scope.
Closure allows a function to access variables from its outer function even after the outer function has finished executing.
Example: function outerFunction() { let outerVar = 'I am outer'; return function innerFunction() { console.log(outerVar); }; }
When innerFunction is called, it can still access outerVar even though outerF

Yes, cloud computing 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.
It offers scalability, flexibility, and cost-effectiveness compared to traditional on-premises computing.
Examples of cloud computing services include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
I applied via Recruitment Consultant and was interviewed in Nov 2019. There were 5 interview rounds.
I was interviewed before Jan 2021.
Round duration - 70 Minutes
Round difficulty - Medium
This was an Online Coding+MCQ round where we had a total of 50 MCQ questions and 1 coding problem. The coding problem was of easy to medium level but was a bit implementation heavy.
Design a data structure for a Least Recently Used (LRU) cache that supports the following operations:
1. get(key)
- Return the value of the key if it exists in the cache; otherw...
Design a Least Recently Used (LRU) cache data structure that supports get and put operations with capacity constraint.
Implement a doubly linked list to maintain the order of recently used keys.
Use a hashmap to store key-value pairs for quick access.
When capacity is reached, evict the least recently used item before inserting a new item.
Update the position of a key in the linked list whenever it is accessed or updated.

This round had 1 coding question in which I was first required to explain my approach and then discuss the time and space complexities. After this , some basic questions from OOPS and Java were asked.
For a given singly linked list, identify if a loop exists and remove it, adjusting the linked list in place. Return the modified linked list.
A...
Detect and remove loop in a singly linked list in place with O(n) time complexity and O(1) space complexity.
Use Floyd's Cycle Detection Algorithm to identify the loop in the linked list.
Once the loop is detected, use two pointers to find the start of the loop.
Adjust the pointers to remove the loop and return the modified linked list.
ArrayList is implemented using a dynamic array while LinkedList is implemented using a doubly linked list.
ArrayList provides fast random access but slow insertion and deletion operations.
LinkedList provides fast insertion and deletion operations but slow random access.
Example: ArrayList is suitable for scenarios where frequent access and traversal of elements is required, while LinkedList is suitable for scenarios wher...
Abstraction focuses on hiding implementation details, while inheritance allows a class to inherit properties and behavior from another class.
Abstraction is the concept of hiding the complex implementation details and showing only the necessary features of an object.
Inheritance is a mechanism where a new class inherits properties and behavior from an existing class.
Abstraction is achieved through interfaces and abstract...

This round had questions from OS and OOPS. The interviewer also tested my problem solving skills by asking me some puzzles in the end.
Piping in Unix/Linux allows the output of one command to be used as the input for another command.
Piping is done using the | symbol
Multiple commands can be piped together
Piping allows for the creation of complex command chains
Example: ls -l | grep txt
A static variable in C is a variable that retains its value between function calls.
Static variables are declared using the 'static' keyword.
They are initialized only once and retain their value throughout the program's execution.
Static variables have a default value of 0 if not explicitly initialized.
They are stored in the data segment of the program's memory.
Example: static int count = 0; declares a static variable 'c
Tip 1 : Must do Previously asked Interview as well as Online Test Questions.
Tip 2 : Go through all the previous interview experiences from Codestudio and Leetcode.
Tip 3 : Do at-least 2 good projects and you must know every bit of them.
Tip 1 : Have at-least 2 good projects explained in short with all important points covered.
Tip 2 : Every skill must be mentioned.
Tip 3 : Focus on skills, projects and experiences more.
I was interviewed before Nov 2020.

The test was in the evening which was not too late. It was conducted on Hackerrank which is a very common platform and was hence familiar. There were 26 questions:
Q1: Coding Question
3 languages were allowed: c, java8, python3
Q2 - Q26: Multiple Choice Questions
You are provided with two singly linked lists containing integers, where both lists converge at some node belonging to a third linked list.
Your task is to determine t...
Find the node where two linked lists merge, return -1 if no merging occurs.
Traverse both lists to find the lengths and the last nodes
Align the starting points of both lists by moving the longer list's pointer ahead by the difference in lengths
Traverse both lists simultaneously until a common node is found, which is the merging point
Tip 1 : Practice competitive programming as much as possible. It's never too late. Start now. But it is important to practice before appearing for the paper.
Tip 2 : Try to start making projects early on as it plays a major role during the interviews.
Tip 3 : Be involved in extra curricular activities and events like Hackathons even if you don't win all of them. It gives a lot of exposure and experience.
Tip 4 : Don't lose touch with your core subjects.
Tip 5 : An internship/training from a good organization always helps (though don't lose hope if you don't have it).
Tip 6 : Focus on your communication skills along with your core subjects as it helps in giving a good impression during the interviews.
Tip 1 : Maintain a good CGPA (above 7.5)
Tip 2 : Mention your projects as they are noticed in the interview
Tip 3 : Having an internship experience especially from a good organization helps
Tip 4 : Focus on extra curricular activities too
Tip 5 : Do not put things you are not sure about
