Meta Data Science interview questions

Low offer: Their final offer is 50-60K lower than what I was told originally. So the business is definitely struggling. Inappropriate conduct with candidates: One of the interviewers spent 10 minutes pressing me on a question about a subtraction function(A,B). It's either A-B or B-A. I didn't remember, so I said we could look at the documentation. After not getting the answer for a couple minutes, this person got frustrated and yelled at me "I'm the documentation. I'm telling you that..." I was shocked that an interviewer could behave this way. Variable skills among interviewers: There are definitely strong technical people, but the data scientists' skills vary greatly. One was struggling to understand how AVG(CASE WHEN ....THEN 1 ELSE 0 END) could calculate the % of certain condition. I was in disbelief.

Completed the behavioral interview, not too bad with emphasis on my past experience and interest in the role. Lots of talk about the culture of Meta, but job responsibilities were a bit vague.
