Looked at this website, read their view book (get familiar with the double helix curriculum!) and picked four activities that I wanted to talk about during the interview (they ask you to pick four and list them at the beginning of the day, so it's best to come with an idea of what you want to write down.)
What impressed you positively?
The students were amazingly nice, not super stresed, social and fun. The school is really nice and the faculty were really approachable and engaging.
