Commvault Junior Engineer Interview Questions
& Process

So, first round was like general aptitude and predicting output for code snippets. Around 200 people applied for this. Then, they shortlisted 40 students for the second round. We were given a demo banking website and had to find as many bugs as possible, suggest improvements, and then upload the code to a server. After that, 7 students made it to the third round, which was a face-to-face interview lasting about 40 minutes. They asked typical questions like IPv6 vs IPv4, how to hack a banking site, how to test an alarm clock, and backing up a large enterprise's data on Google. They also covered networking concepts like NAT, Default Gateway, TCP/UDP, Public IP, internal IP, and some file and process questions. The fourth round was a telephonic interview with 3 shortlisted students. The questions were more abstract, like developing a website and migrating it to the cloud, including steps and payment gateway association. They also asked about Subnets and why they're useful. Finally, the fifth round was an HR telephonic interview with 2 students, where they asked the usual HR questions about interests, parents' jobs, native place, internship experience, and attendance.

It started with a multiple choice test on CS topics. Then there was a round where they give you an app to test and you had to find as many bugs as possible and check tool behavior, they rate you on how critical the bugs are. After that, a technical face to face interview. Lastly, an HR formal round.

So basically the first thing was this online coding round, it had 5 questions that were kinda medium difficulty and we had 70 mins to do it in C or C++. If you passed that, then there was this intense 6-hour coding round. Right after that, we had the HR and technical interviews.
