Infosys Digital Specialist Engineer interview questions

For DSE, the first round is often a coding-based test (online or via a coding-challenge platform, such as through campus-drive / contest-based entry). Common format: 4 coding questions to be solved in ~ 3 hours. Difficulty: one easy, one medium (often greedy/algorithm), one hard (often dynamic programming / DP). Based on performance in this test (number of problems solved, test-cases passed), candidates may be shortlisted for further rounds.

The interview process for the Infosys Digital Specialist Engineer (DSE) role is structured but very smooth and supportive. It usually starts with an online assessment, where they check your problem-solving ability through coding questions, aptitude, and a bit of computer science fundamentals. The test is straightforward and focuses on how well you think through a problem rather than just memorizing concepts. After the assessment, shortlisted candidates move to the technical interview. This round is conversational and feels more like a discussion than a strict interview. The interviewer typically asks about your projects, how you approached challenges, and your understanding of core topics like Python/Java, OOPs, data structures, databases, and sometimes basics of cloud or automation. They also test your reasoning and real-world thinking by giving small scenario-based questions. The final step is the HR or behavioral round, which focuses on understanding your motivation, how you work in teams, your learning mindset, and how you handle pressure or deadlines. It’s usually friendly, and they mainly want to check if you’re a good fit for the Infosys culture. Overall, the Infosys DSE interview experience is professional, structured, and candidate-friendly. They look for clarity in thought, willingness to learn, and the ability to apply concepts—not just technical depth.
