Pompous Job Descriptions/Requirements

A lot of people run into situations these days where they see a job that they are highly qualified for, but the job description is so pompous and exaggerated that it would appear that they're unqualified.

And then we have HR people, who create these pompous job descriptions, running around claiming that they're receiving piles of applications from 'unqualified' people. Even though such individuals often have better knowledge of the job, through personal and professional interaction, than even the HR clerks themselves.

Anyone else seeing a lot of this? Job descriptions that have been deliberately set to require a lot of things that are either trivial, simply unnecessary, or impossible to attain? Ever faced the wrath of being in contact with a HR clerk who defends such nonsense? Ever gotten a job despite not being precisely what, in theory, they 'wanted'?

I personally see this mostly in the public sector, where managers routinely 'rig' job descriptions to favour friends, insiders and even certain minorities (ie: French speakers in the public service) -- or merely because the incumbent (who retired) had a whole laundry list of "qualifications" and they want a sort of perfect replication. But surely it exists in the private sector as well.
