Infosys Digital Specialist Engineer interview questions

Infosys DSE Interview Experience I recently appeared for the Infosys Digital Specialist Engineer (DSE) interview through HackWithInfy, and it was an amazing learning experience! Round 1 – Online Coding (HackWithInfy) 3 questions — Easy, Medium, and Hard. Focused on logic, optimization, and clean coding. Round 2 – Onsite Technical (at KIIT University) Started with a 30-minute coding test (2 questions, medium-hard level). We had to attempt at least one. After that, the technical interview began. I was first asked to introduce myself, followed by one Advanced Java question. Then I had to write code for Merge Sort ,BFS & DFS and answer theoretical questions like when to use BFS vs DFS, and explain in depth. Overall, the process was challenging, concept-driven, and very insightful. Grateful to Infosys for the opportunity and the learning experience!

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.
