Applied in February 2014, and interviewed in early April 2014. They give you 14 questions that you have 15 minutes to look over. Then you will go to the room where RJ and WT will take turns asking the questions while they jot down notes. Questions were based on disease investigation procedures. After this interview you will be asked to complete a pretty easy epidemiology exercise. They never called me back after the interview, despite saying they will.
