The first part was a screening for both sides to know each other. The second part was a technical interview with two interviewers. It started with a simple coding exercise, where I was asked to revert a string. Then I was asked some general questions about Android and best practices, what a flow is, the difference between a cold and hot flow, how I would organize the architecture in a project, etc. For the third part, I had homework to implement a simple app project using an API to present it in the next interview. The third part had 3 interviews in a row: the first part was a quick talk with the HR manager, in the second part I presented the app, explained it, and then questions were asked to change it, and the third part was about system design, where, according to the requirements, I had to design a system, with parts of the backend and the app.
