I applied through my school'd job board and I received an email shortly after that telling me that the Category Manager would be calling me for an interview over the phone (I was in Paris at the time, and the position was to work in Belgium). The phone interview lasted a little bit over an hour, was very friendly and asked all the regular "marketing questions". It was even easier that most marketing interviews. After that I got an invitation to have a face-to-face interview in Belgium. There I had to do a case study, presented to the team and had a short interview.
