2 rounds. One of them was a call and then next day I was called me for an interview in the office. The overall attitude was rude and condescending; they behaved as if they were doing me a favor. It was clear that the professional interviewer didn’t appreciate the fact that I was able to answer their questions. HR manager was great, she was nice. That is why I accepted the offer finally. There was a 2 professional interviewers in the meeting room and the HR.
