Meta Software Engineer interview questions

Recruiter chat, code screen (2 problems), and an onsite consisting of 2 more coding interviews and a system design interview. All coding questions were from the top 20 leetcode problems in the last 6 months.

The process of the interview was good and well arranged: screening, 2LC, system design and behavioral. However, the system design interviewer was not ready, at the beginning of the interview he said let me pick a question , I solved a question the same way in the Alex xu book but seems he didn’t like it and he wrote a feedback which was not true at all, and when I asked questions at the end he underestimated me, it was offensive!
