The interview lasted 45 min. The whole interview took place in English except one question in French. There was only one interview which was conducted by the head of hr and 3 staff. The employment offer took 2-3 months to materialize

Basic questions. Don't stress, so many candidates for all positions so you are proably not going to get the job anyways. Just be friendly and have a good time. They are saying I need to enter more words.
