1-st round of interview was really nice. We discussed with interviewer my experience and projects and solving technical tasks about language syntax and algorithms. 2-nd round was with team lead and it was awful. As soon as he entered conference room he gave me task but it doesn't have enough entry data to solve it. When I was asking him about, he didn't giving me, but just saying how you think. So atmosphere was nervous to think about solving task. And I skipped interview
