First I had a short online video call with HR. Next I had a online video call with the hiring manager. The last interview was in their Mannheim office with the hiring manager and three further team leads. They mostly asked questions about my CV and experience. They also showed me around the office and answered any questions I had. Unfortunately, the company took very long to make a decision and in the meantime I had gotten another job offer. Almost two months after my last interview I got a rejection.
