The problem I have identified is that the people and or systems who do initial screening don't really know what they should be screening for.
You might have a real technical position that you need to fill requiring like archaic engineering knowledge. Then they do the screen and remove everyone who doesn't have a resume polished to whatever the latest MBA format is. Which removes a bunch of weirdos that are perfect for the job (because let's be real, it requires a strange skill set) and you are left with a bunch of candidates that can talk out of their ass perfectly, but don't actually have the knowledge or skills needed.
Then you get this bubbly Kevin who is good at communication when you really need Kwame who just wants to be left alone working on the technical problems.
