I didn't see this post pre-edit, so I'll assume that it wasn't too bad. If you were suggesting some kind of affirmative action (as someone hinted), then that really wasn't the case.

The reason I applied to the Foreign Service is because it is a meritocracy. It all came down to how you did on the test, and later the interviews/case studies.

It's unfortunate that it's your dream job and you didn't get it, and I sympathize, but the Foreign Service admission process is one of the most transparent ones I've seen. The first step is passing a test, and anyone above a certain threshold moves to the next step. There are more tests, and anyone above those thresholds gets on the list to be accepted.
