That is all fine, but what they are doing is discriminating against a certain kind of human being. No other industry behaves in this way. In other industries you would get a job interview regardless of how you gained your accreditations or experience (as long as the required credentials have been met). Then and only then would you be judged, i.e. at the screening/interview process. All employers in other industries acknowledge the natural elements of 'circumstance' and 'difference', they do not tar everyone with the same brush just for the sake of simplicity.
