As I was not based in Amsterdam at the time, therefore I had 2 skype interviews with HR, the person I was replacing, and the CMO. After, I was invited for a face to face interview at the HQ. I did not need to prepare anything for the interview as communication skills are essential for my role. However, I've learned from other colleagues that joined my team that some roles require preparation/assessments. The CMO had several industry related questions. So, in depth preparation is recommended, especially if you are aiming for a role in one of the commercial departments.
