You also have to deal with delusional hiring managers. A few months ago I remember seeing a comment on here from someone who had kept job listings up for years while hiring because he couldn't find anyone with the "right experience". Clearly there was no actual imminent need to fill the role and he was just hoping that some superstar would stumble across it, but he kept insisting that this counted as "really hiring for the role".

aka the person willing to work for a fraction of their worth.
