Practicing Awareness of Microaggressions

I was surfing the internet looking for a job one day, and I came across an add for a law office. I called them because I sent my resume over. They guy was so nice we talked for over 30 minutes. After such a great conversation I was asked to come I've ASAP to meet everyone else. I was so excited that they were so interested in me I rushed right over. When I arrived and told them who I was the man looked at me kind of strange. He asked me if I was the same person he just talked to. After enough convincing we finally went into the conference room with the others. The mood went from happy to disappointed very fast. Here I was the only black person in the room with 8 white men and women. I felt very uncomfortable because they were all just staring at me and not engaging at all. One of the men turned to me with no greeting and told me unfortunately I am not qualified for the position. Even though my credentials at first was all they were looking for. This was very hard for me to take in because I was so sure I landed a great position. I guess by the seeing my name on my resume was hard for them to tell my ethnic background. Now when you fill out applications they ask for your ethnicity, and often times I am reluctant to answer because of my previous experience.
