I don't get how to get the Ursus job? It's extremely difficult to increase all of muscles, anal top, oral top, anal bottom, and oral bottom when you don't have a job. Like, you definitely can, but it costs money and you don't have a job... so... it's difficult. You also can't get a second chance even though there is a link for it. The link just does nothing.
EDIT: Ok, well it's not actually that difficult if you know the requirements ahead of time. It just takes a long time if you need to catch up on reqs while in the middle of trying to get the job.
