Urban Dictionary describes ghosting as “The act of suddenly ceasing all communication with someone the subject is dating, but no longer wishes to date. This is done in hopes that the ‘ghostee’ will just ‘get the hint’ and leave the subject alone, as opposed to the subject simply telling them that they are no longer interested.”
The recruiting-world equivalent of “ghosting” is when a candidate goes through the interview process, and the recruiter ceases communication with the interviewee without any explanation. And no the “thanks but we hired someone else” perfunctory email sent to the candidate four months later doesn’t make up for it. That’s the recruiting-world equivalent of the “It’s not you, it’s me” lame excuse.
