There were only 2 interviews. First was the technical one. It was very friendly and nice, it wasn't just a bunch of questions like "What is a Broadcast Receiver?". No, it was more like a discussion, we talked about technologies, architecture, problems in Android and overall experience. Second interview was with a product manager. It also was very friendly, I was told about company, project, why am I needed, what will I do. Then we talked about me, my personality, what I like and what I don't. Overall it was very nice and fun talk. Also, I have to notice the professionalism of HR department. They were the best HR-managers I have talked with. Overall, everyone in hiring process was very kind and friendly.
