I passed to the second round og the interview. The first part was quite easy and relaxed. The HR was nice and friendly. During the second round there were two people (Team leader and an assistant). They asked me more or less the same questions as in the first round. The questions were typical. However after the interview they said that they were going to make me a "surprise". They gave me a computer (the assistant was sitting next to me) and asked me to make some tasks in excel. I didn't expect that and I was really lost. So, if you know excel well, you shoudn't worry about that part. But if you don't I would recommend you to learn some basic formulas, pivot tables and the simpliest tasks.
