Two rounds of interviews on site after the test, the first one was pretty less interactive as the manager didn't show much interesting on me but the second one was good, at the end I didn't get any offer.

Two rounds (45 mins for each) for different group of seniors. The questions are depended on the interviewers' style. In the first interview, I was asked some basic understanding of operating system, data structure, etc. The second interview was full of behavior questions.
