The positive thing was the interview time arrangement. They wanted me to select 2+ slots from a timetable for my availability. Then they informed me about the precise interview time. Although the timetable was not selectable (actually this part of the webpage did not work) and I wrote my availability in the optional comment section. I took part in the first step of their interview only. The interviewer was a good-tempered person and asked me about regular matters. Before asking any question, she described their company and at the end of the session she explained the process of the hiring which they’ve already posted on their website. It seemed that she just wanted to ask some questions and finish the interview. (doing her tasks and that's it) After two days they got back to me about their rejection decision (with usual ceremonies). The point was they addressed someone else in the email (which wasn’t me). I wrote to them about the mistake and never got any response.
