I got an email yesterday morning that sounded like a lead. The usual, "we're impressed by your profile, would like to talk about an opportunity, blah blah blah"

Scheduled a meeting, expecting a recruiter call. Got a salesman trying to pitch me an automated application service, that charges $50 per application and something like 10 weeks salary on placement

Told the guy to pound sand

Another company that does this is ladders. You'll see a posting, use it to apply, and then they'll black hole responses to your application unless you pay up. They'll also spam the ever loving shit out of your inbox
