Saurabh Thakur’s Commvault Interview Experience

The online assignment was a 60-minute test. To begin with, there was a section for language preferences, such as C++ and Java. I opted for Java, Following that, around 20 minutes were allocated to Java Object-Oriented Programming (OOP) questions. In the remaining 40 minutes, there were three coding questions. These questions covered topics like Dynamic Programming (DP), backtracking, and graphs. They were of a moderate level of difficulty, similar to what you might encounter on platforms like LeetCode. In this round, candidates were required to correctly solve at least 8 Object-Oriented Programming (OOP) questions and 2 coding questions to advance. Following that, there was an 8-hour coding round in which candidates were tasked with implementing various concepts related to the operating system and Linux. The problem statements encompass data backup, recovery systems, and a music player. Essentially, participants had to create a file system. There were 6 milestones that candidates needed to complete, and there were eliminations every 45 minutes. During this round, mentors would also inquire about the code candidates wrote and ask for a comprehensive explanation of their solutions. One have to optimize my design pattern by implementing a file system with features like adding, deleting, and creating hard links and soft links using Java and Object-Oriented Programming (OOP) principles exclusively. One couldn’t rely on any inbuilt libraries for this task. I spent the first 2 hours brainstorming and refining my idea, which was eventually approved. Out of the participants, only three of us managed to advance to the next round
