There were two stages in my case. I believe usually there are 3. First interview was with the line manager, then one with HR BP, and with the Director of the department. The interviews took place in the office headquarters. Extremely pleasant people and interactions - relaxed and chatty. I enjoyed that it didn't feel overly stiff and the conversations flowed naturally. The longest interview stage was with the HR BP - which I haven't experienced previously. However, it's a good stage to cover whether you and Casumo actually align. Every person answered all my questions as well.
