Coordination. First scheduled interview nobody showed, something unexpected can pop up, but message even 5 minutes before (or after) time would be better than nothing. Interview was rescheduled on next day, again no message or anything, I slept it off. Third time, it finally was an interview. Some questions I couldn't answer. Feedback was promised in a 1 working day. The interview. The interview consisted of probably all possible theoretical questions, some short code examples that I had to explain and a very short practical coding challenge. Feedback. Got feedback in 3 working days. In a cons list were questions that I did answer correctly too. Overall impression. Poor approach to whole process. Too many theoretical questions, some not needed at all for doing described job. Almost no testing of actual practical skills. Biased feedback, depends on a somebody's mood.

At first we have general interview, next day was technical interview. There were two interviewers, they were very kind, but you newer know if your answer is good or not. Great thing was, that they send in rejecting mail all aspects that I need to improve.
