I initially had to submit a short presentation video. Then a first interview was organized and it lasted 60 minutes. It was quite easy and we mainly spoke about the role and my past professional experiences. I then reached the second interview stage and the situation was quite different. It lasted 90 minutes and had to answer to at least 20 questions, way more specific. I also had to make a presentation and present it during the interview. What wasn't helpful was the support from HR that actually misled me suggesting that the topic of this interview would have been my educational background and provided me with insufficient details on the presentation I had to prepare.
