The interview was mostly professional and friendly. The first stage was an online test with questions about Java and a couple of coding tasks. They were not too complicated, and the time allocated for the test was more than enough.

The second stage was a conversation with an engineer. We discussed both tech and behavioral questions. There were no very deep tech details, just enough to prove that I have solid basic knowledge. I answered all questions, and the feedback from the engineer was positive.

Several days after the interview, HR called me. She told me that I performed well but that they were stopping the hiring process with all Russian citizens because of some 'visa problems.' I'm not sure which problems exactly, because Russians are still able to get an Austrian working visa normally. This was sad, because these guys run a really interesting project.
