It was two steps. A written exam and a interview with tech team. The written exam was made on a recruiter office and later I went to the interview in the company. The interview was with other two developers and it was divided in four sections: 1. They asked me about my skills in iOS development; 2. They asked me about my experience with large teams and some development methodologies; 3. They asked me personal questions. The last part was an algorithm test on a white board.
