I think they are not interested in hiring anyone who is not Chinese, through out the interview they specifically grilled and made fun even though my answers were correct. You are hiring folks who have 6+years of work experience and asking them University quiz questions? Clearly the person who was asking them was googling it as well. Its very easy to do a process if you want to reject someone, just google random quiz and ask as if a person is chatgpt. Funny that they have fancy titles of Director, what a complete joke. Wouldn't work for such clowns for a million buck!
