It is a group interview but not really like an interview. It's very informal. They have you do tasks designed to reveal your creativity and ability to work as a team player. One task is a game with blocks where you work with others to build a structure according to a picture everyone gets to see once and must remember. Then each takes turns putting a block on the pile to build the structures according to each person's memory of it. Another task, each person is given a scenario of some sort and must sell it. Not a bad experience.
