Learning COBOL is the easy part. My understanding is the hard part is becoming familiar with insanely expensive, proprietary mainframe platform that’s you’ll find in most COBOL work. I know IBM has some sort of self training material, but I’m not sure if it’s enough to go from zero to qualified. Most work I see in the area seems to want established domain experts, not hackers who learn just enough to be dangerous.
