Start with HR phone interview, and then the phone interview from hiring manager. The final interview is an onsite interview with the whole team. The location depends on different project.
I applied online. The process took 4 days. I interviewed at Sinopec (Pekín, Pekín) in Nov 2018
Interview
2 rounds of interview. 1st round with the group, then with the institute. 10 plus interviewers for each round. Quite much pressure at first, I think it was intended so.
