Two interviews; each has 2 coding problems; medium to hard leetcode; for each problem, solve in ~15 to 20 mins. They go straight to the coding problem; no introduction; At the end, they will let you ask anything about Meta

I got to the final. It was very long, and the interviewers were not friendly. I was interviewed on ML system design three times; the first two told me 50%, and in the last one, the guy was very hostile.
