Not that I necessarily doubt these numbers, but by personal experience these always feel awfully low (even jobs paying to TVöD on entry level should put you above the median). Especially when going for larger enterprises I can only recommend negotiating - a lot is possible and realistic beyond the 90th percentile with even moderate experience.
Readit NewsI work at a global corporation with 50,000 employees. Even though I've never been at Google I felt every pain point this video was getting at because our company is trying to implement all of this stuff right now.
"Oh you want to go to production? Here's a list from A-XX stating what you need to accomplish that." Thing is I thought they actually handled this gracefully when I started because lots of requirements were tiered with various criteria you had to meet to move up (mostly for brownie points).
But then one day the Tech Execs lose their minds and decide "everything needs to meet all criteria for every single process." You want to create an S3 bucket to store data? That will be a week of submitting paperwork and another month of meetings and approvals from various teams you've never heard of. Plus you have to register your schema, implement data quality checks, unit tests, regression tests, get a PR and CO approved for your central config change, remediate any CVEs in the tooling that you used, and build all of this using our in-house CI/CD platform we created because we're just soooo special. Now you're allowed to launch. Oh wait, NO because we've put the entire corporation on hold from launching new systems for the last calendar year because we're still trying to agree on the final process everyone needs to follow to go to production.
It's surreal how universally so many orgs makes the same mistake of trying to throw more and more process at problems.
Literally every point you made applies also at my workplace. The optimist in me hopes we work at the same place, but I fear that your last statement might just be the truth :-)
Tl;dr public service employees earn pretty average
