If you are preparing for a mainframe job with a skill set of COBOL, you would first like to prepare on the commonly asked cobol interview questions. There are plenty of websites on mainframe offering free interview questions on cobol. Going prepared for an interview makes you feel more confident to others who are less prepared. JCL interview questions, DB2 interview questions and CICS interview questions are also easily available on the internet and you may want to be prepared for these as well if the company offering jobs require these skillsets. If you are really out of touch of mainframe technology and want to brush up on the basics then you may want to go through few mainframe tutorials available on the internet.
