I had 3 interviews, two first 1h interviews on skype to talk about my background, experience and what the position would require. I spoke with the team leader during those and it was very enlightening and fluid, I really liked the discussion. I then had one final on place interview where I met the members of the team and had some open questions to resolve on a whiteboard. Overall I liked the interview, most of the questions were directed to my specific background and projects so I felt at ease.
