2 Rounds, each one was delayed. I waited additional 30 minutes for the first round, 45 minutes on the second round.
First round was done by my future manager, who interestingly enough only wanted to see work done in one of my previous work places. Later I learned, that Home24 would eventually only be a copycat of that company.
The second round - surprisingly enough - was done by an external swiss-army-knife-guy that did not really know which questions to ask.
