Commvault Software Engineer interview questions

The selection process comprised of a coding round, a power programming round, 2 technical interview rounds and a HR round.(Every round was an elimination round) The first round comprised of 3 coding questions and 15 Mcqs related to basic oops concepts, DBMS and OS. The second round was basically the difficult part. It was a continuous coding round for around 7 hours wherein we were given a basic structure of a file system and we had to design the file system as per the requirements of the question and in the starting hours we had to design the classes and if the design impressed the mentor then only we could do the further coding of the functions. The mentors were there to help us with our doubts regarding the question.And there was a progress check in almost every hour and students were asked to leave if the progress was not good enough. Next round was the Technical Interview round where they focused on OOPS concepts, DBMS and OS. I could reach up to the second round only.

First there was aptitude and java mcqs. If shortlisted you will be giving a coding test in which they will ask ds algo based questions. After this they conducted sort of a mini hackathon. Where you will be given a big problem statement and will be asked to code it.
