The assignment was just right difficult. I think with it I could properly show my main knowledge of programming the Android apps. It took me about 15 hours of work, which is a bit more than they assumed, but it was my fault I needed more time than it was planned. There was no deadline. I just needed to let them know the estimated date, when I was planning to finish it, but they said I can extend the submission deadline if I'd need. The technical interview was nicely structured by topics (eg. architecture of project, handling data, frameworks etc.). I liked if I didn't know or understand something I got full explanation. Also I got full feedback about my assignment so I know what I did by their expectations or if not, what I could do better or differently.
