I applied online. The process took 2 weeks. I interviewed at ByteDance in Sept 2021
Interview
Chinese interview. The entire interview process is in Chinese. Asked the interviewer if one can speak English, and they said no in Chinese.
Extremely awkward interview as one is forced to speak technical terms in Chinese without preparation.
Be very careful when applying to this company if you do not speak Chinese as your first language.
