A "ghost job" is a job that isn't real. It's a job for a company that isn't actually hiring, or at least hiring for the role advertised. More than 1,000 hiring managers were surveyed, and 27% of them admitted that they've left these jobs up for over four months, never intending to fill them.
New phenomena? Sort of! Companies used to run "blind ads" in newspapers to accomplish some of the same things.
