No surprises there
It is widely understood that the resume scanning systems are crap at best. In fact the scanning systems are so bad that they're risking irrelevance. The job seeker needs to find a way to get through that first-pass selection cut. I've been making lots of applications at companies where ex-coworkers sit in the hopes that they can help my resume get raised up in the pile.
This is part of the reason why companies have referral systems - the general employee base handles the first level of screenings. Even more effective is to develop a relationship with a hiring manager, establish your credibility and suitability to the job, then that hiring manager contacts HR and tells them to put through the paperwork and generally get out of the way. That can take quite a long time. I had a couple of interviews via this method - in fact the one hiring manager said that he didn't have the time to waste waiting for an application to trickle through the application management system.
Posting as AC as I'm currently "in transition" and have been trying to get around Human Resources functions for a solid year. HR is the biggest hurdle and detriment to getting the right people into the right jobs.
