Jobz...

So I'm curious... Does anyone have any idea on the basis of job applicants being called back? (Or is it random "Pull from the stack"?) I've put in an application to nearly every retail/restaurant/small business in the area, and I've got nothing back... 

Do people really not hire because of things like "Overqualification"? Just cuz I've went to college means noone wants me for the basic jobs anymore? — feeling determined.
