Start with my own self-introduction and the interviewer's self-introduction first for five minutes, then a couple of technical questions for like thirty minutes, and in the end, questions for the interviewers about the company.
I received the interview a few weeks after applying online. During the interview i was asked by the interviewer about my past experience and also some other related technical questions.
