I'm brand new to dealing with recruiters and have read some interesting things on both TechExams and online. Some are more honest than others. This one recruiter would like to recommend me to a company but first needs my resume in Word format because "some HR systems don't accept PDFs."
This immediately set off warning bells, since ALL systems I've encountered accept PDF. My guess is he's lying so that he can change some things about my resume, which tampers with the integrity of it. Heck, maybe I could sign it with my private key and then password protect the editing.

After all, he SAID he just wants it in Word format for submission purposes, so a read-only Word document wouldn't be relevant, no?
My question to you guys is what's your experience with this? Do they want to add their recruiting company logo to the header of your resume, or are they actually going to go in and screw around with the content and change stuff? That seems highly sketchy if so.
