I did two rounds of interviews.

1. The first round was 30 minutes with the project manager. It included some general questions about me and the types of testing I performed, why I wanted to join Trivago, if I knew Trivago's working model, and some company introduction.

2. The second round was with the same project manager and a test lead. It involved one SQL problem to solve in 10 minutes. I felt it was not very easy to solve but managed to partially solve it. The next set of questions had a diagram for which they gave a very complex explanation and asked for testing strategies, which I was able to answer. Overall, the interview went well, but later they said I was not through to the next round.
