I get lots of job postings from agencies, many of whom I'm not familiar with. I've heard it said (on this forum and elsewhere) that many such postings (and those on sites like Monster) are not for real potential jobs; they're either a way for the agency to build up a database of resumes, or maybe the hiring company is researching the talent pool or something.
Is there a way to tell if a job is fake?
I assume that if I see the same job from multiple agencies, they didn't make it up. Although maybe the hiring company did.
