Interviewing at Commvault
What the process looks like, and what Commvault is really testing for.
Commvault interviews are a mix of recruiter screening, behavioral evaluation, and multiple rounds of technical work. The technical bar in the data is strongly shaped by Python plus backup or restore fundamentals, with very prominent C/C++ style topics and system design or design-first technical work in many reported paths.
Across roles, you are tested on problem solving and communication, plus stakeholder alignment and cross-functional collaboration. The technical topics most emphasized in the collected question data are Python, backup or restore fundamentals, data management, networking fundamentals, and system design or architecture, and the same data shows C as the most prominent technical language topic and project management, business analysis, financial analysis, and marketing analytics as prominent role-aligned areas.
The process varies in how many rounds you see, but the reported structure consistently includes initial screening and behavioral components, and then ends with decision-maker level fit checks in some paths. Candidate reports show difficulty skewing toward medium and hard, and offer rate in the aggregated candidate reports is 0.0%, so you should plan for tough technical hurdles rather than assuming every loop ends quickly or favorably.
In the question data, C is the most prominent language topic (percentile 100), while backup and restore fundamentals is also at percentile 100. Even if your primary language is Python, expect at least some depth that ties storage or backup concepts to technical implementation details.
