I was called by phone to arrange an on-site interview a few days after I submitted my job application. During the interview, I was first shown around by my would-be boss, the office manager, and then I had a conversation with them. This lasted about 20 minutes. Then I had an interview with two more senior colleagues, this happened on Zoom in one of the office's conference rooms. Lastly, I had an interview with the HR representative – this part was in German. My German at the time was around level B2, so this part was difficult, but the interviewer was friendly and helpful without compromising her demandingness.
