Museum Hack interview questions

This company was fun to interview with and definitely invoked each interviewer's creative side. All went well and I was able to proceed through to the rest of the process. We were then given the opportunity to show our skills and give a tour of the museum. I did extra research and even revisited the museum to get my footing and then the rest was a breeze. The presentation day came and my natural abilities started to come out. I was telling stories, giving fun facts, showing extra pictures on my iPad slides and other people were coming up to listen. Well, I felt great and I knew I did great... but it didn't occur to me that it should have felt a little odd that only one person was evaluating my presentation. I was told all went well, I took my directions well and did an amazing job... well not two days after, I was terminated from moving forward by people who had not been present at my tour...this was odd. Then I started thinking about the dynamics, not only was I being evaluated by one person which leaves a big open room for subjective criticism...but there were seemingly no other people of color (within this company) leading tours in museums full of works done by people of color. I'm not sure exactly what happened...but it leaves room for my imagination to run wild as to why I was randomly terminated from moving forward with no substantial feedback... Especially after being told to my face that I did a fantastic job. This job is not rocket science, which makes all of this even more offensive... especially when having a degree relative to this.
