First I had a general phone interview. They asked me about my CV and some questions about my work experience all revolving around the leadership principles. A few days later I obtained an email and was invited to the office in Munich. There I had 4 interviews back to back and had to do an excel test at the end. The questions were all life related and on my past experience. Questions overlapsed and the interviewers showed little understanding that i was tired after so many interviews.... a few days later i got an email saying I was not taken without any explanation. I flew in extra from Madrid for the interview and expected at least some feedback.
