There were two interviewers, one Taiwanese and one Indian, so the interview was in English, but after the report and answering the Indian's questions, you could use Chinese. The Indian supervisor mainly wants to know about things other than your resume, and will ask you if you have any cloud projects, what tools you have used, and whether you have done any LLM-related projects, and so on. Taiwan engineers mainly ask machine learning related knowledge, such as how to deal with insufficient data, how to adjust the batch lr and so on.
