This was an off-campus opportunity.
Round 1: Online Assignment
In this round, I had to design a Memory File System with various functionalities like:-
- mkdir: Create a new directory.
- cd: Changes the current directory. Support navigating to the parent directory using .., moving to the root directory using /, and navigating to a specified absolute path. Anything that you can do in a normal terminal. Since there is no user-level implementation, ~ and / should take you to root.
- ls: List the contents of the current directory or a specified directory.
- grep: Search for a specified pattern in a file. PS: It’s a bonus
- cat: Display the contents of a file.
- touch: Create a new empty file.
- echo: Write text to a file. ex – echo ‘I am “Finding” difficult to write this to file’ > file.txt
- mv: Move a file or directory to another location.
- cp: Copy a file or directory to another location.
- rm: Remove a file or directory.
Round 2: Interview (CS Fundamentals + DSA) (90 Minutes)
After 2 weeks I got the call for an Interview round. This round started with an Interviewer introduction and then followed by my introduction.
I mentioned CS Fundamentals (OS+OOPS+DBMS) and DSA in my introduction.
The first half of the interview was based on Object Oriented Programming questions:-
- What is the difference between class and object
- What is the use of a constructor
- How is the constructor different from the Member Function
- What do you mean by Nested Class
- Rules for Visibility and Accessibility in Inheritance
The second half was based on Data Structures and Algorithms Specifically on Linked List questions were:-
- First, I was asked to Implement the Singly Linked List from Scratch with functions like:- Insertion at the head, at the given position and tail and then similarly for deletion.
- Second, I was asked to Find the middle of a given linked list
- Third, I was asked to Reverse a Linked List using Recursion
- Fourth, I was asked to check if a singly linked list is palindrome
I was able to tell all the oops questions along with the coding questions and my interview went on for 90 minutes although it was supposed to be 60 minutes only.
The interviewer said to me at last that HR would contact you for 2nd round of Interviews but the opposite happened I got the rejection mail in the evening which was very disappointing as my interview went very well and the interviewer was very much satisfied and had sad me something else, seems that my luck was not with me.
