The interview process is very disorganized and fails to give applicants an opportunity to understand the company, it's measurements, and your role as a prospective employee.
My process began with a recruiter - their own HR has no one with English-speaking ability. After basic introduction by the recruiter, an interview was scheduled with 2 employees of the Shanghai office (I was applying for a job in Beijing). The panel included a foreigner who had less than a year with the company and a Chinese manager of some sort. The foreigner was not impressive as an interviewer, asking such questions as "tell me about yourself" and "why we should hire you". My questions about the company dominated over half of the 1 hour interview.
Afterwards you may be asked to submit a teaching demo if you're applying outside of China, as I was. I sent such a demo and received an offer within 24 hours. Their process had stated earlier there would be a second interview with the company's owner/president who works in the Beijing office. They decided that interview was not necessary, but I insisted on it nonetheless because I felt it important to understand the Beijing work environment.
I was instead given an interview with Myra, corporate HR in Shanghai who does not speak English and could not answer the most important, specific questions I wanted answers to. I could only ask for more money as they would not arrange the interview I requested, which they agreed to pay. Effectively saying they would rather I don't know what I'm getting into rather than make sure I'm a good fit for their company.
Overall their interview is an extremely dehumanizing experience and is given the same level of care a granny may use to pick out her vegetables at market. If you can't "pass it", then it's likely the first interview you've ever had. You won't be missing out on anything in either case, so my advice is to really explore alternatives before attempting to join this company.
