Firstly, I spoke with the HR through a phone call including introduction and motivation which lasting around 10 min. And then i received the email of final interview inviattion, i was been told two senior engineers will be there as the interviewer but actually, it was an HR person and a senior engineer who were my interviewers, both of them arekind and friendly. firstly, there is a brief introduction part and a high level case for your to analysis with requiring u to answer 6 questions, the process was lasting 30 minutes and after that, all the question were about ur past experience and soft skills and 3questions about technical aspect in the end. u also have time to ask questions.
