I am a foreign employee, hired for a position in China. So the process I describe is specific to this situation.
I had 4 phone interviews:
- First interview: with the research team manager and an engineer from this team. Questions were focused on my background, especially related to the technologies I developed during my PhD. There were also private questions such as why I want to move to China, do you I have relatives there, do you speak chinese, etc. And I was asked for my salary expectation.
- Second interview: with the target department director, who asked similar questions (I am afraid I don't remember exactly).
- Third interview: with another research department director, who asked mostly technical questions.
- Fourth interview: with the HR, but it was actually a call to tell me that I passed all previous interviews, and give me the official salary offer. I could not negotiate at this point, so be careful to mention your salary expectations early in the process. Then I asked a bunch of question to the HR, as that was my first abroad job experience, and also to check the advantages I could get (honestly almost none).
The 4 interviews were on my mobile phone in France, and the sound quality was terrible. I advise to ask a Skype interview instead, for people who are hired in the same process.
