One the HR contacted me said there's a matched position for me and the team leader would like to have a phone screen with me. We did the phone screen on the next day. The interview started with some introduction of my projects in my resume. He did not have interest on my project, this part was pasted very quickly. Then he asked me some technical questions about different kinds of sensors on a smart device including there working principles and applications. Finally some behavior questions were asked like have you made a decision that not good for now but benefits for the future.

Very unprofessional process, starting from recruiter communications, then onsite interview scheduling and the team who did the interview. They bring people from way outside your area to judge you, not only that, they also bring undergrads with 2 yrs experience to judge a PhD applicant with 5 years experience. So outside your field (i.e. Mechanical engineer to judge and electrical engineer) plus being much less qualified and experienced than you (i.e. Undergrad with 2 yrs experience judging a PhD with 5 yrs experience). Because of this they ask questions from nowhere and mean nothing.
