Ghost jobs postings refer to listings by employers that either aren't real or have already been filled but never lead to an actual hire. Recently, there has been a sharp upward spike in the number of ghost job postings, with some sources mentioning that in 2023, only 4 out of 10 job postings in popular job seeking platforms had led to actual hiring, a sharp drop from 9 out of 10 postings in 2020.
