I've only once ticked of roughly 95% of job requirements. I didn't get the job. They actually cited the 1/20 requirements I didn't fulfill and said they can't hire anybody who doesn't have that. They wanted a 100% candidate. Looking through the list of the things they listed as must haves and that they wanted an internal candidate I showed them it is statistically very unlikely they would even find a better candidate…
They wanted a 100% candidate. You sure about that? Maybe they wanted an easy way to tell people no. Maybe that 1/20 requirement was very heavily weighted compared to the other 19. Maybe they didn't really want to hire anyone at all or wanted to hire a specific person, but had to make a job posting for political/legal/policy reasons...
Of course, it's also plausible that they just never took the posting down.
