In about 1980 I tested for the Post Office, got high-ranking scores, put in for an interview, was told not to bother unless I was a minority female.
Somewhat same time frame and same results. I needed some kind of preference points that a white male that was reliable, quick learning and hard working, counted as zero( hell basically negative)
No biggy though. I"ve never made a post about it. Its life. While I despise a lot of things including where I"ve worked the last 15 years and how they screwed me on my retirement so far, its what it is and make the most of it and move forward.
