Yeah, that's what I've thought too - in my (plenty of) interview experiences, I have to specifically ask if the job listing was written by HR or by the hiring manager, if I'm interviewing with HR or a hiring manager, and so on. Basically - HR useless and retarded; hiring manager typically knows what they're looking for and wanting.

Of course, that's not to detract from big boy multinationals trying to abuse lax labor regs for slave laborers
