Application and if successful, invited for a formal one-one interview. They do really well with time, I arrived early and was called in at My appointment time. They don't do much to relax you if you're nervous, they go straight into the protocol regarding your driving licence and will start by calling DVLA to check any points or convictions, they then ask you for all the documents and don't really make any small talk. I felt the interview was quite cold and when you're trying to inflict passion it becomes hard as you think you're talking to a robot.
