I was one of the early RHCE (Red Hat Certified Engineer (IIRC)) around 15 years ago.
I let the certification expire - I couldn’t find anyone to hire me to do that, even working at a consulting firm at the time.
If the situation has changed that radically, I guess it might be worth dusting the corners of my brain.
A lot of companies are opting for CentOS. They keep a few mission critical’s on RHEL but by and large CentOS is re-shaping the landscape.
Wow, you’re one of the few. Actual RHCEs in the wild are hard to find these days. We’re a HEAVY RHEL shop with Windows as our backbone. I’ve made my gravy off of Microsoft for 20 years, but I’m an advanced Linux user; and I can tell you that my knowledge of Linux was part of the reason my boss hired me. If you can bat from both sides, you’re a force to be reckoned with.
