What Commvault asks in the DSA round

Commvault pairs medium DSA with data-protection domain questions — backup, deduplication and recovery — plus OS and file-system fundamentals.

Across the 12 questions on this page, the weight sits on these patterns:

How to prepare for the Commvault interview

  1. 1. Start at the top of the list above. The patterns are ordered by how often Commvault uses them, so the first two or three buy you the most coverage per hour.
  2. 2. Solve by pattern, not at random. Doing eight dynamic programming problems in a row is what makes the ninth recognisable in an interview — jumping between topics does not.
  3. 3. Tick problems off as you go so the gaps are visible. The per-pattern counts tell you which Commvault topic you have actually covered.
  4. 4. Write the approach before the code. Commvault interviews are judged on the reasoning as much as the working solution.
  5. 5. Pair this with the pattern guides when a topic is new, and the system design sheet if the role is senior enough to have that round.
  6. 6. If this is a campus or off-campus drive rather than a lateral move, the placement preparation guide covers the stages around the DSA round — aptitude, core subjects and the HR interview — in the order they actually happen.
