This is a site that thrives on fights, not debates (which implies that minds can be moved). It's genuinely sad.

I would only add to this that in IT (as well as other industries but my experience is in IT) applicants are often pre-chosen due to various social and professional networks on the part of all involved including non-managers. Friends of friends. Yes, a lot of time they go through the sham of announcing and collecting applications but the fix is in and no one objects because squeaky wheels in IT often become unemployed. It's not just Blizzard; it's everywhere. Who you know is often what tips the balance; not what you know. The many posters here who loudly bellow about how objectionable it is not to be chosen on qualifications apparently have no idea that this is the norm, not the exception.
