It starts with a set of IQ test by HR, followed by interview with 2 senior engineers + 1 division head in a small room. Be prepared of the technical questions. They also ask about your knowledge in semiconductor industry. The interviewers could be friendly, but that doesn't imply any better chance. Employee referral is very much helpful.

Got contacted by hiring manager and scheduled an interview by next few days. Interview with a panel of senior engineers. Knowledge in semicon process seems to be a key point.
