Used to be very specific instructions about mailing a resume to an address with a reference number. And advertised only in the newspaper. But Immigration said they can't do that one anymore; has to be the same submission methods (email, webform, whatever) as an actually open position and advertised/listed in the same places too.
But they'll still have the other tells, which is very specific experience and education requirements which happen to line up exactly with their preferred candidate. Sorry, we did our best, but we can't find any local candidates with a 4 year BS degree, a minor in Clown Studies, and 3 years experience with very specific software that isn't used many places (experience most likely obtained at the hiring company during internship or while on OPT; or while on H1-B if this is in support of a green card, rather than in support of H1-B).
The HN job board is much more likely to produce a qualified candidate.
Or is it just chatter from the grapevine?
We did have many work visa employees though.
We worked with Healthcare clients. Big ones.
Or any public sector job where positions have to be posted but you already have your internal hire, son-in-law, or cousin lined up.
But, it's mostly just rumor I've heard.
If they don't suck, the guy fails the labor certification and may have to wait a year to apply for the green card again. However, he doesn't lose his job, and the qualified candidate never gets an interview.
So yes, it's pretty standard for the companies to post openings they don't have.
But I really doubt they post on the HN jobs board. Most will go through more formal channels.
