Send CV and motivation letter and then wait for the first HR call. I waited approximately 1 month. After first check call, I was invited to the interview with the group manager. The interview questions were so awful. The manager was basically reading the most typical and general questions to ask the candidate from his paper. It was not a dialogue, and I had to start it myself. Then I was given 1 week for the case study. After the final interview they offered me a junior position.
