Straight forward. Initial call with HR took about an hour. It was mainly for the company information. Same day received one online coding test afterwards. Response was very quick and hiring steps are clear. Coding test seems easy and even though I cleared all visible test cases, got rejection saying it was not adequate. It was expected as I did not use any high performant advanced data structures intentionally.

I had an initial call with a recruitment specialist, then technical interview with the team (consist of 2 parts - team presentation of the project they are working on and problem solving) and a final call with the CTO. The position was in Saarbrücken. The interviewers were really kind and have answered all my questions.
