It’s worse than that. Most of these environments are in the stodgiest corner of those companies. I worked with one a long time ago as a consultant where we struggled with an authentication related issue.

The response from the service owners was that they weren’t going to switch to a new, unproven methodology. In this case the “new” thing was around since like 1989 (this happened circa 2003). They still use whatever they were using today.

As a new hire, you’re screwed. Anyone getting into mainframes is insane.
