Online video interview with the interviewer (HR) who is based in mainland China. The whole process lasted ~30 mins. Very typical first-round interview with HR. But the experience was not very good. I feel very uncomfortable. The interviewer didn't introduce herself at the beginning of the interview, instead, she asked directly to challenge me to see how much I know their company. The worst is that she asked me if I have children or if I have any plans for a child.
