I know the call handling system has updated but used to be a process where they gave you a sheet beforehand and you had to rate yourself confident to loss confident, would recommend putting confidence in every area. It will depend on who you have marking you as every person is different.. I conducted interviews myself and how you look and present yourself is a big factor as well as your communication.

1 hour telephone interview with 1 member of staff. Brief conversation in French about your year abroad or studies. Lots of information given to process and make notes then example scenario of a break down.
