What's the largest company you've worked for? A lot of big, older companies, are just so messed up that its just not worth it. How do you do this? Well you have to find the specific form, or specific person who does the thing, who is that? no one knows. So that provisioning of a vpn and getting in jira might literally be like a month of work.
I've worked for S&P Global, so pretty large. If you don't have an account that you need, then you need to be tenacious, which of course is super annoying. If you don't have an account on a system you should, it's 100% on you after a while.
