First step was, that I sent my CV and link to my web portfolio. Then they invited my for an interview. That was surprisingly short - they knew everything about me from the CV, so I have only get an assignment to make covers based on two topics. It was told me, that I can make more than one version on each. I had a week for it. After that, they invited me for another interview which was much more concrete. I learned all the details about the job and they offered me to get into to a working process for fourteen days to learn more. After those two weeks we finally made an agreement and set up salary conditions.
