The HR department is root of all evil at times.
My current position I was already hired for by my previous employer from another company. He said all I had to do was contact the HR dept. and get the paperwork done.
The gal called me every day because she couldn't understand why I wasn't selling my home to relocate to the office out of state.
She couldn't wrap her head around the fact that only an idiot would sell their residence, purchase a new residence for a “Start-Up.” LOL. Then to your point. You have to spend hours and days explaing your resume to them. Just forward it to the dept. manager.
Let the department managers decide what they need and let the department secretary write the ad and sift the responses.
It would be a lot cheaper and faster.
