I applied through college or university. I interviewed at Infosys (Neu-Delhi) in Dec 2025
Interview
The interview process mainly focused on DSA and core Computer Science fundamentals. There were also several resume-based questions where the interviewer asked about the projects and technologies mentioned. Additionally, SQL problem-solving questions were asked, similar to the type of problems available on LeetCode (around 50-level SQL practice). Preparing these topics in advance would be very helpful for the interview.
