After the initial HR chat they gave me a homework todo. It was an easy home work, needed about 5 hours to do. On the technical interview we have discussed the homework that I've submitted and also some technical questions. After the technical interview I've had a three days trial with them, where I get the chance to work with the team that they wanted me to join. Of course this was also part of the interview process and the future teammates were reviewing you as well afterwards.
