The interview took 2 weeks with a pre-test and an onsite interview. in the pre-test I am asked to select 1 on 2 questions depends on which team I want to apply, I finished it and send back within 1 week. The onsite interview was at the company's meeting room. The interviewers are friendly, they asked questions to check your basic cs algorithms and system concepts such as Process, Thread, Memory, IO, etc.
