You are invited to a room, where a manager will speak to you informally in regards to the role and the responsibilities. Nothing technical, there are no competency based questions or numerical tests. Afterwards they will invite you back to a group interview where they will tell you what the role entails. At this point basically everyone who attends are given the position.
