2 rounds - I got a telephone interview & face-to-face interview 2 weeks later. They checked my language skills and my ability to prioritize tasks. My first task was to reschedule some fictional meetings of middle management staff. My second task was a case interview. I do not remember exactly what was the case about but certainly aimed at how I deal with stress and deadlines. 2 HR employees were asking some more questions about my past experience. They were really friendly then - unfortunately I cannot say the same about their behavior after having me on board.
