First code test, answering some questions and writing an essay about a certain chosen problem. After that there are 2 technical interviews with coding and techincal questions. It was fairly easy, However, the person who interviewed me was not very competent and told the HR department untrue things, which I later found in my feedback.

I was asked about nearly everything from my uni's curriculum and beyond. There was one practical task, which tested your algorithm's knowledge (20 minutes) and technical questions about data structures, DBMS, data protocols etc.
