first you have to do a online screen-on + micro-on test, kind of LeetCode test. Then you have 2 technical interview with technical leader of the futur department , and the last interview with a manager. I got all my interview successful and apparently "high note" then I do still not get the offer from Huawei and I should still wait.

Only went for the first round of interview. It was a F2F physical interview at their office, where it was with a senior engineering and a department head. They went through the resume and focused on projects and past tasking that are relevant to the role. Following that it is 2 algorithm based questions, roughly leetcode medium level of difficulty.
