Do you need special training to write an Employment Posting?

I am retired but have recently started to browse through the on line job sites to help out a friends search and I have to say I have no idea what some of these job requirements really are...For example...

Experience with Contractual Hygiene.... This was for an entry level Admin job. Are they looking for someone to keep the papers clean? Are they looking for someone who knows how to run an anti virus or spell check?

And another for a receptionist position with a software company.

Consistent high quality of interaction with all drivers and principles.

Do you have to take a class to learn how to write bull shit like this and is there a contest for the most obtuse and obscure job requirements....I have a few nominees.
