Started from around 9:30am until 12:30pm, lasting longer than 3 hours (but it really depends on who you're interview with). 3 Management and 1 PM took turns during the whole interview. The whole process was mostly conducted in Chinese, but since they do international business, initially they asked me to translate a short tech brief published by a relevant magazine; later after basic questions were inquired and the corporate vision explained, one of the managers asked me to answer the later questions in English, which lasted about 20 minutes.
