Airbnb Customer Support Representative interview questions

I was interviewed for role of Customer Rep. in Airbnb. The first interview was through Hire Art, and then I was invited to last group interview in Dublin. It was like a workshop. It was a group interview and they expected from candidates that they almost know everything about Airbnb related problems with Airbnb system. I felt like I am in a horse race, and plus when seeing other candidates how ambitious they are, I felt a bit strange.
