It's a meta tag, and its description even reads that it shouldn't be used anymore:
Career development questions are off-topic for Stack Overflow. DO NOT USE - Removed as part of "The great Stack Overflow tag/question cleanup of 2012" - See link in Tag Wiki for more information. (to be reviewed for closure only)
Since that event has long since passed, can we circle back and remove/clean up/burninate this particular tag?
EDIT: Look at the tag synonyms, too: career, career-advice, employment, and job-hunting. Can we put some fire to these, too?
