HR part of communication was greetful yet not accurate: HR didn't tell me that live coding will be without usage of Internet and without IDE helpers for namespaces and classes names, I really don't ever try remember all this needed stuff as in usual work I'm just using Visual Studio. Because of this, 90 minutes were not enough and the interview was failed. This miscommunication made me mishappen of the whole inteerview process. By the way all HRs and interviewer were friendly and polite
