The ad indicates the law of supply and demand.
The supply is so great the demanders can get a real bargain in price
The same btw is true of young lawyers I think
Most likely the "ad" indicates wishful thinking on the part of the employer rather than an actual job opening. Hiring managers frequently indulge in escapist fantasies of "the perfect subordinate at a bargain price".
There are many such "employment postings" in various media - with advanced professional credential requirements and entry-level pay scales, or even unpaid internships. Those jobs are not real.
At best, less than 50% of advertised jobs result in a hiring action within six months of the posting.
When there is a real need to get a job done, the hiring manager will take the next presentable candidate that comes in the door.
It is no great wonder that "millenials" do poorly at job interviews. It is a crazy-making process and they get constant mis-direction.
This has not changed at all in the last 40 years either.
