First, we had a coding task for 1 hour, it was an implementation of the simple app. A process was divided into several sections, after completing each interviewer was changing some aspect of the app and I coded it. After that, we had a talk about mobile, web, databases and some questions about how I would have implemented some real-world app. Overall coding part was pretty easy, the interviewer was a polite and really great guy, he even helped me to find some little mistake in my code during the coding part.
