Waited in lobby and was told thank you for coming and to take a seat. They offered me water which I declined. Then I was escorted by an employee through the office to the side of the building. The interview was done in an RV, which I'm told is where they have brainstorming sessions and smaller group meetings. The interview was formal but very relaxed. It was myself and 3 other people of various positions who asked question based on work, experience, personal life, as well as any questions I had about the job or company.
