Infosys Programmer Specialist interview questions

I recently participated in the Infosys interview process through HackWithInfy and got selected for the next round in Category 1. The onsite interview took place at the Infosys office in Sector-62, Noida. Round Structure: Online Coding Round (HackWithInfy): I received three coding questions and performed well enough to qualify for Category 1. Onsite Coding Round (45 minutes): At the Noida campus, I was given one coding problem to solve on their platform. One of the problems was related to Binary Trees, and another involved Graphs. I tried the graph problem, but only a few test cases passed. Technical Interview: After the coding round, the interviewer asked several DSA questions, including topics from trees, graphs, DP, and problem-solving. SQL questions were fairly straightforward. They also asked about my projects and resume. I struggled a bit with the DSA part — while my intuition was correct, I couldn’t articulate the exact solutions clearly under pressure. Overall Impression: The interview was fair, and the questions were a good mix of coding, theoretical concepts, and project discussion. However, it was challenging, especially the DSA part, and requires strong clarity in algorithms. Advice for Future Candidates: Prepare well for core DSA topics, especially graphs, trees, and DP. Practice writing clean, efficient solutions under time constraints.
