Mainframe Developer

Infosys’ interview process usually starts with a timed online assessment covering quantitative aptitude, logical reasoning, and a short coding exercise in COBOL or Java. Successful candidates move to a technical interview where they are tested on mainframe concepts, CICS, DB2, and problem‑solving ability. The final HR round assesses communication skills, cultural fit, and salary expectations. Overall difficulty is moderate; thorough preparation of core mainframe topics and practice of aptitude questions greatly improves chances.
