I applied on the career website. I was asked about two weeks later to complete a video interview. The questions were recorded and I had to answer in 2 or 3 minutes (depending on the questions). At the end of the video interview, there was a coding test.
A week later, I received an invitation for an onsite interview! As I was located in the South of France, they invited me to the Sophia-Antipolis office for a videoconference (the interviewers were in Cambridge). We talked about my previous experiences and at the end, I did some exercices on the white board.
