Process
Two mid-level LeetCode problems, and some in-depth discussion of computer vision.
The interviewer focused mainly on the numbers of projects (like how to achieve a 30% speedup).
Not in the best mood; the interview consisted of 40 minutes for coding and 20 minutes for chatting.

Cons: Most people speak only Chinese in the office.
There are a lot of extra hours (unpaid).

Basically, they imported the 995 (9 am to 9 pm, 5 days a week) culture from China.
Local management and HR are dismissive about the overtime issues, considering them to be isolated cases.
Delivery expectations from the Product Manager are unrealistic, yet they don't want any pushback from engineering.
Many new hires are Chinese students, not helping with adopting Australian culture.
