In my interview I got 6 questions out of which 5 required an answer and the last one was filler where we can say anything if we want to add something extra.
The first 5 were normal questions where they will ask about why you want to do this course, what you can contribute to the class, why you chose EDHEC , future goals , etc.
You don't need to prepare anything just be true and confident and the rest would be fine. Lastly remember to see the course structure as they may ask about it.
All the best!!
