There were several interviews: English, tech via Skype. And face-to-face in Kherson office. English interview was the first one and determined English level. I was asked some common questions and mostly speak about myself: my work, hobbies, life, travels etc. It took about 30-60min/ Tech interview took 2hours. There were a lot of questions about Android SDK, Java, OOP. After those two interviews I was invited to face-to-face interview in Kherson office. This interview was with chief of Kherson office and HR. I got offer on this interview.
