I actually applied for a different role but the HR department called me if they can forward my application. The same day, someone from the department called and we arranged a personal interview in Munich. The interview was on a Friday afternoon around 3 with the team leader and the intern supervisor of the department. It took around 45 minutes. An hour later, I got the offer by email. Really nice and easy interview. BUT: No travel cost compensation is offered unless you ask them before the interview!
