With no more than 5 minutes chat in the elevator I was given a writen test with questions from various fields. It was not that hard but I could have prepared better. After I finished the test I met with two interviewers who checked my answers in my test and where I didn't know how to answer they resolved the question together with me. A major con to this interview is that it's already been 3 months and I got no answer. No big deal anyway, I got a job the next week somewhere else.
