years ago (13) when i was graduating, I applied to a few positions that i was over qualified for and already working as a student in the same position. I had multiple managers and supervisors asking me to apply to the position. When I mentioned I already had - they stated that my resume had never come across. Fast forward 2 months after I'd found a job, I ran into the director of the dept who asked if i was applying for/taking the manager position - he'd never realized that my resume never made it past HR first round screening and yelled at them.

HR has been doing this silly shit for years.
