These are peoples’ livelihoods and time they’re fucking with. At minimum we should get a rejection email so we’re not left out in the cold.
I always try to look up a recruiter’s superior whenever I talk with one. If they ghost me, I then send an email to their superior.
I don’t usually get a response, but I like to fantasize that recruiter getting their ass handed to them for ghosting me. It helps me sleep at night.
