Meta Data Scientist interview questions

Got scheduled through a recruiter. It takes 2-3 weeks for the interview to get scheduled. Focus A LOT on SQL or Python (mainly dictionaries and lists) depending on what what you choose.

Phone interview with Data Scientist after conversation with HR. The interviewer was professional but did not followed the interview format described by HR - for example, I had only 3 minutes left for SQL assignment at the end of the interview instead of the announced 20. I am not sure what the skill set they are looking for - I got a feeling that ideal candidate is the one who knows FB products and industry terminology well and can type fast.
