Short question and answer forum with two staff members asking questions. Buisness formal for dress, everyone appeared on the same level of experience. Very relaxed atmosphere. There were several people interviewing for the position.

The HR Director, Hiring Director, Senior Director, and a Project Manager interviewed me in a conversation style interview that lasted two hours. Each person embellished on the previous person's conversation and we went through about five rounds. It was not difficult but was quite specific.
