Mainframe Developer

Infosys typically conducts a three‑stage interview process: an online aptitude and coding test, followed by a technical interview focusing on mainframe fundamentals, data structures, and problem‑solving, and finally an HR round assessing communication skills and cultural fit. The difficulty is moderate; thorough preparation of COBOL, JCL, and basic programming concepts, along with mock tests, greatly improves success chances.

Infosys is recognized for its collaborative work culture that emphasizes continuous learning, mentorship, and employee well‑being. The company provides structured career progression, regular upskilling programs, and a balanced approach to work‑life integration.
