The experience I've had with outside recruiters in the past 10 years is atrocious, though. All they're looking for is warm bodies to toss at a company, and hope one of them sticks. No or limited experience--they still want to present you...after modifying the resume you've sent them in Word.
Today's outside recruiters are inexperienced in and ignorant of the field ("Your last job was a fitness trainer??"), and borderline unethical.
I'm still surprised so many of them are in business.
