426 developer mainframe interview questions shared by candidates

Technical round: Basic JCL, COBOL, DB2, VSAM questions were asked. Scenario based File operations. SORT tricks. IDCAMS utility related questions. No need to read any book, if someone really worked in any project can answer the questions. Interviewer didn't prepare any questions, he talked with me and based on my response he was asking questions. There is a company CGI, I attended months back and before 2 days I attended the again (both telephonic). In both, the interviewer asked really same questions and in the same manner. Such a STUPID!! Managerial Round: Mostly Project related, Client related, my roles and responsibilities were asked. HR round: HR remembered me after 2 days of completion of managerial round. However, no communication since then.
