Fortinet

After passing the skill test (coding on computer), I received the interview from three people: my manager, my manager's manager, and a senior software engineer.

A 3-hour technical interview with the team, asking basic algorithm and data structure and system design and my experience in ML. The team was nice and the interview process was very informative.

The process is fast. From screening to providing an offer is within a month. Questions are focused on detailed network security. There are no LeetCode or system design questions. The interview was in Mandarin after they knew I could speak Mandarin.
