I got a call from HR manager. He was very friendly. When he heard that I don't have a valid work permit he politely refused myself as a candidate, because there are a lot of native citizens applying for this position. Nevertheless, I was able to get a lot of useful information from this interview. I found the competition rate for this positions, it was about 5 person per one position. Than we talked about the whole process . He said he would ask me simple technical questions based on my experience. If I passed that I would go to technical assessment, where another engineer asking more difficult and deep questions. He said also that they would like to know people's troubleshooting skills and how they are thinking. It means never say "I don't know", always try to answer the question some how.
