O2 (Czech Republic) interview questions

Interview was pretty easy - no homework, no project, just the interview. But this might be different for different positions (I've heard from some colleagues they had to deal with some analysis at home).

Two rounds, quite short time between them. First was with the HR representative and my potencial superior. Scond with the department manager. I had to explain in more details my work responsibilities in previous jobs and also prove my command of English (written/verbal).
