Assignment, then a technical interview about the it and technical questions about ios and swift. Then a conversation with the VP R&D. The conversation was short and at the end the interviewer said that even so my assignment was not good enough and in fact they wasted my time. After I asked them why they decided to continue for two next stages, he told me that actually I didn't pass the first stage but they wanted to let me chance. ofcourse they didn't give me chance and I was disqualified in advance
