Had a first screening interview (~20mn) over skype. Then had a full in-depth technical interview with the tech team (CTO/Mobile lead/Engineers, 4x50mn) over skype. Range of the questions was large, going from architecture, design patterns, testing, Java-specific features, development philosophies etc. Had a few "brain quizz" questions with code to write live. The current mobile developer showed me the code's structure of the current project. A couple days later I got an answer (positive).
