Very standard steps, they are using an online system to arrange the interview, the first round is with a Singapore hiring manager, and another seems like technical department members. They are asking about some questions regarding my experiences, and gave some assumptions in some cases, about what I will do, for example, for system migration, what to do to make it work. But the information given is very limited, you need to assume the current background story and system cases yourself, which I think the questions are too open, better to give some current situations.
Then the tech member also asked about some questions related to program management, it seems he expects more from senior PMO, not just regarly management.
