It was a waste of time. Very unprofessional, unmotivated HR 3 times missed all appointments, even without letting me know. After short typical screening I just got to the next step - interview with manager, wich went very positive. As result I got an invitation for full-day face-to-face interview in Hamburg (although I applied to a position in Berlin). At that point I've already wasted too much time with them, so I asked for some solution in Berlin (otherweise it would take me 5-6 hours only for traveling). HR just lost interest and reported that all open positions in this year are already closed and they'll get back to me later in 2016. Long story shortly: friendly, but unprofessional waste of the time.
