Meta Data Science interview questions

Through employee referral, I first had a non-technical phone screen with a recruiter. I was then asked to do a live coding interview with a FB data scientist (split screen; half video half coding). The interviewer was a nice and well meaning person (even gave hints), however I failed to solve a (in hindsight) quite doable coding challenge. I was asked to apply again in six months or so.

Ater referred by my friend, I got an email from a recruiter and completed a survey asking about my education and experience. Then I got a 15 min phone screen with the hr screen, which includes some product questions and SQL questions. After that, I had a video interview with one of the data scientists, and the interviewer was incredibly friendly.
