2 interviews: The first one was face-to-face in Wolfsburg, Germany. It was pretty hard and took more than 1 hour. Typical interview questions and some technical questions through my CV has been asked by a technical manager. Conversation was NOT relax and friendly, but more like it was serious and professional. Then, I was invited to a second interview which was on a telephone. It was extremely difficult and technical questions were asked regarding my past experiences, studies and projects.
