The whole process took around 1 week. I applied through the website and got an email with an invitation to the 15-minute talk with my future supervisors. The same day after this call, I got an invitation to the second round and a task to prepare for. I was invited to the Garching office to present the task. On the day of the second interview, I presented my slides, and we talked about responsibilities. The next day after the interview, I got an offer.

Very smooth and easy going, felt more like a chat than an interview. My interviewer seemed genuine in learning more about each person they were interviewing and asked more personal questions rather than about the skills.
