It is no secret that Muthu’s refreshers are colloquially known as "Interview Bibles" in the IT sector. Part 2 specifically targets the type of questions asked for Mid-Level and Senior-Level roles. The Q&A format at the end of chapters helps candidates articulate technical concepts clearly, bridging the gap between knowing the syntax and understanding the logic.

While "Part 1" typically focuses on COBOL and basic mainframe concepts, often delves into more advanced topics required for production support and development:

The by Muthu is a popular guide specifically designed for mainframe professionals preparing for interviews or looking for a condensed technical review. While Part 1 typically covers the basics of TSO/ISPF and COBOL, Part 2 focuses more on advanced application development, database management, and operational utilities. 📘 Key Topics in Part 2
