ConocoPhillips ONRR Analyst interview questions

I went through a staffing agency and was told I was a great candidate. I took an Excel test and scored 90%(not bad since I haven't manipulated Excel in 9 years and do not use it in my everyday job function). I have a BS in Accounting and graduated 3rd overall with a 3.7(they were looking for a min gpa of 3.2). That coupled with my Excel score was good enough to garner an interview. It was a last minute interview. I was told the day before at 4pm that they wanted an interview for 9am. I agreed to 3:30pm. I got there and they interviewers were 15 mins late, first of all. Then they seemed genuinely disappointed that I was actually black. Interview was brief and casual. Behavioral questions, which I handled to the best of my ability. They seemed disineterested, disengaged, and their demeanor just read negatively. I was told later by the staffing agency that they chose not to hire me based on my Excel score, the same score they saw PRIOR to the interview. I took it as code for she's too smart and too black. The look on their faces said it all when they realized I was the person behind the resume. I pretty much knew then it was going to be a no, so I waited on the staffing agency so I could hear the "official" reason. I know its Bartlesville and Conoco is the head honcho in those parts, so its no coincidence that black people don't live there.
