Many headhunters post fake ads. They post the ad to collect resumes, rather than having a specific opening that matches the ad.
On most Internet job boards, you don’t always know who is posting the ad. Even if you say “I refuse to answer ads by X.”, you could always be responding to a fake ad. One headhunter even said “Why are you sending me a resume even though I spoke with you already?” I replied “Put your name in the ad, and I’ll know to not answer.”
Many sleazy headhunters ask “Tell me all the places you’ve interviewed and the hiring manager, so I don’t double-submit you.” They are merely fishing for information, trying to find out who else is hiring. I always say “I haven’t had any other interviews.”, even if that’s a lie. I’m offended when a headhunter is fishing for leads, rather than trying to help me. Besides, any non-sleazy employer works with only a few headhunters and has policies to prevent double-submissions.
I recently found a short-term contract. I stopped sending out resumes.
There are a few headhunters that I haven’t heard from in months. Now, they’re calling me.
It’s obvious what happened. They saw I stopped responding to their fake ads. They realized I found a job.
They want to find out where I’m working, so they can try to place other people with the same client! They are calling me now. They aren’t interesting in placing me. They are merely trolling for information, trying to find out where I’m actually working.
