brsj, I saw your post on another board where it had more detail. As I recall, you had only been there a month when the position opened up and the VP or whomever hired a friend/acquaintance of his to fill the slot to which you aspired.
I don't think there's anything to add other than what others have already commented. While I think it was a really lousy employee relations move to tell you they would interview you and then not do so, there isn't anything that overtly suggested your race was the issue. Favoritism based on being pals or a relative of the boss is not prohibited. It's also possible they really were looking for different professional attributes that those you had, significant as those might be. Or it could all be a lot of B.S. and they just didn't want a black in the managerial role.
At present though, there just isn't enough to go on to offer an opinion as to whether your race had anything to do with this. You may wish to speak to an employment law attorney for an expert legal opinion before deciding whether you want to pursue a claim of prohibited discrimination. I suggest that because filing an EEOC claim against your current employer is a pretty big deal and an even bigger deal if your race honestly had nothing to do with their decision. I'm not suggesting they'll retalliate but obviously pursing legal action isn't going to make them feel warm and fuzzy about you.
