I applied online. I interviewed at ByteDance (Shenzhen, Guangdong) in Sep 2021
Interview
In the first round, a HR specialist who picks up your resume will conduct an interview with you in english. If proceeding to the next stage, then the manager will interview himself or herself, asking you more questions about the business or technical stuff.
3 interviews in total, questions are almost the same by different people. If it's offline, they will show you around the nice office, pretty cool. People are very kind and smiling.
