how to prepare for mainframes to clear interview?

Very simple. You have to prepare all the modules like JCL, COBOL, VSAM and DB2. Most of the companies repeats same questions upto 60%. So prepare well for those 60%.

One simple idea is.. Whenever you comeback from any interview, maintain a notepad and note down all the questions which they asked in the interview. Next time when you r going to any interview just look into that notepad and go.

Follow the above process then surely you will get the with in 5 r 6 interviews.

All the best
