Round 1 - Coding Test 

(1 Question)

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.

  • Q1. 

    LRU Cache Design Question

    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...

  • Ans. 

    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.

Round 2 - Face to Face 

(3 Questions)

Round duration - 60 Minutes
Round difficulty - Medium

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.

  • Q1. 

    Detect and Remove Loop in Linked List

    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.

    Expected Complexity:

    A...

  • Ans. 

    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.

  • Q2. What is the difference between ArrayList and LinkedList in Java?
  • Ans. 

    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...

  • Q3. What is the difference between abstraction and inheritance?
  • Ans. 

    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...

Round 3 - Face to Face 

(3 Questions)

Round duration - 60 Minutes
Round difficulty - Medium

This round had questions from OS and OOPS. The interviewer also tested my problem solving skills by asking me some puzzles in the end.

  • Q1. Can you explain piping in Unix/Linux?
  • Ans. 

    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

  • Q2. What is a static variable in C?
  • Ans. 

    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

Round duration - 60 minutes
Round difficulty - Medium

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

  • Q1. 

    Intersection of Linked List Problem

    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...

  • Ans. 

    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
