4 rounds in total. first is HR phone call, asking about your backgrounds, reasons of moving, expectation for job and compensation. second round are DS in the team who also may be your future peer or lead. Has a coding test and asked about past projects. Third round is by a DS manager, focused a lot on my past experiences. I prepared for some ML knowledge points but didn’t ask any. Final round is done by head of DS. Mostly general questions about my expectations and plans. 1. interviewers are friendly. they are ok doing the interview in Chinese if you prefer. 2. interview doesn’t have very strict structure. Partly because they wanted to customize the questions based on my experience. But also not very professional. 3. based on the interactions, I felt the team isn’t very advanced in technology. maybe they are good at machine learning as a individual (I don’t know), but I didn’t see a strong infrastructure or clear strategy, or a deep understanding of the businesses problem they are trying to solve. 4. HR is totally incapable to decide value of candidate. They look at very shallow indicators like YOE or current pay level. But they miss how much contribution they can get out of me, especially when they really need some help in building a more advanced technology.
