It was a video interview. I first had a 20 min self-introduction (including a introdction on PhD and MS thesis topic). After that, the employer asked about questions about persoanlity and working styles.

Managers from 3 department. 15 minutes introduction, then they take turn asking question, but no professional question. After about 1 minth, HR called me to asked some basic question, such as could you take shift? do you accept any relocation?
