Selection board (usually two or three people, including the supervisor of the position and a representative of Human Resources). The team leader will tell you what to expect, and will explain that the board will be recording your answers for later review. Don't let this recording process distract you—it’s a normal part of the interview and necessary to make a complete assessment later on.
Generally they will make a friendly ambience, you should just a follow them and answer the best as you think that you know.
