Real, anonymous reports from people who interviewed for Software Engineer at Commvault, newest first and distilled into what to expect across the loop.
I went through a tougher multi-round flow with heavy coding and a pairing-style low-level system design component across a few screening stages.
I had a smoother interview experience for an SE role where the questions were approachable and the interviewers focused on discussion.
Candidates typically begin with an online assessment that includes data structures and algorithms (DSA) questions, often featuring multiple coding tasks and multiple-choice questions (MCQs) focused on core computer science concepts. The difficulty of these assessments can vary, with some candidates reporting challenging problems and strict platform constraints.
Candidates can expect multiple coding rounds that range from LeetCode-style problems to extensive system design tasks, often requiring a hands-on build or low-level design in languages like C++ or Java. The length and complexity of these rounds can vary significantly, with some lasting several hours.
Technical interviews often involve discussions around candidates' coding approaches and fundamental computer science topics, including data structures, algorithms, and system design. Interviewers may focus on both problem-solving skills and theoretical knowledge, with some candidates experiencing a more supportive and conversational format.
Behavioral interviews are typically included to assess cultural fit, with candidates discussing their previous experiences and how they align with the company's values. These rounds may follow technical assessments and can vary in structure, with some candidates reporting a more streamlined process.
Candidates report a wide range of experiences, from supportive and structured interviews to more demanding and high-pressure formats. Some paths emphasize rigorous technical assessments, while others focus on conversational problem-solving, leading to varied outcomes based on individual performance and interview style.
Many candidates did not receive offers, often citing the need for strong technical skills and the ability to perform under time constraints as critical factors. Feedback from interviews indicates that clear communication of thought processes and effective problem-solving strategies are essential for success.
