Lo, many years ago, I was working for a small company as their one and only technical author. I decided to leave (something to do with a 50% pay rise to go work for a much larger company that wasn't obviously circling the drain and due to go bust within 3 months). I gave notice, and as my then-employer had no HR policy and no HR department (it was management by autocratic whim: one boss and about twelve technical staff) he asked me to hang around long enough to draft a job description and tidy up some loose ends.

So: job description for technical author duly drafted and sent to recruitment agencies. Whereupon we got CVs back by fax. Wildly inappropriate CVs.

I remember one perplexed phone call that I ended after the recruiter at the other end of the line said, "technical author, technical support engineer -- what's the difference?"

So yeah, watch the quality of your recruiters! (Whichever side of the table you're on.)
