I had to do an app that pulled issues and comments from RxJava GitHub. I spent a full day on it. I was told it met the basic requirements but they said they passed on me because in one sentence "your layout files are wrong." Whatever that means. Really? I spent a day on this application for that? Did not get any proof on that either. There is only one Android Engineer there at this time I was told and they must be really picky. Please don't apply here because they'll claim "your layout files are wrong" without proof and reject you.
