Personally, I think my interview was not that easy but I did prepare for it pretty well.
It lasted for like 45-50 mins including those random chatting at the beginning and in the end. I had questions related to my work (what I do, daily tasks, explaining projects I am involved in, if I use French at work, etc), my study (very detailed ones), my internship at school, my career plans, why I prefer to work in Canada, my previous history of studying French. We also discussed education systems between Canada and my home country, mental health issues among teenagers nowadays, pressure from school, parents, and the disadvantage of the advancement of technology. Some other things include why do I want to stay here, advantages of working here comparing to my home country, one thing about my home country that I think is better than that in Canada. She also asked me to describe a piece of recent news that I heard from radio/Internet, then we had a discussion on that as well (comparing people's attitudes towards food & nutrition in Canada and my home country).
It was really like a daily chat, there was obviously more questions during the interview than I listed above. My suggestion is to have a list of potential questions you might get and practice with your francophone friends and/or tutors. Once again, good luck, everyone!
