Meta Machine Learning Software Engineer interview questions

1 recruiter reach out, 1 phone technical interview, onsite interview(2 coding+1 ML system design+1 behavior) and 1 system design follow-up interview. Took already 3 month+ and still waiting for the result.

First approached by a recruiter for a software engineering- machine learning position, followed by a screening interview. I got 2 Medium LC tagged questions for my screening interview. Nothing out of the ordinary. The interviewer was very polite and professional.
