This. And a lot of those places are not actually hiring. The place I work now has had a sign out front for months saying they are hiring....when the truth is that in a few months, they're planning on transferring 20+ employees to another facility in another town completely...so be prepared to move if you want to keep your job.

Those signs can also just be total bullshit to keep the employees happy thinking that they will be getting help eventually or it’s code for “we have an internal person already in mind for this position but must post the job publicly as a requirement”.
