Commvault Interview Experience (On-Campus)

Commvault Interview Experience (On-Campus) 2023
Commavault visited our campus for recruiting for SDE (C++/JAVA) and SDET( PYTHON) roles. If you choose the language as C++/JAVA you will be given an SDE role and for python SDET roles.
First Round: Online Coding round on their platform. The webcam is on. There were 15 MCQ and 3 coding questions. MCQ was based on OOPs mainly and one easy and two medium coding questions.
Don’t remember based on xor.
Second Round: Implementation of Virtual File System. We have to complete their code of the virtual file system. This round was 6 hrs. This whole code was to be completed in 6 hrs.
