Meta Data Scientist interview questions

I had my first interview with Recruiter in February second week. I was asked general screening questions + SQL fundamentals + quick product question about Newsfeed. Don't take this round easily, you might be caught off guard. Then I had my 1:1 video interview with a Data Scientist but the video didn't work properly, so ended being similar to phone interview. It was a Product design round, how would you develop <fill in any FB product>, metrics, experimentation basics Then had virtual onsite with 4 data scientists. The format and focus was clearly given by the recruiter. From my perspective I did 3 interviews well but the last interview was bad. The main problem was video conferencing, we couldn't be on the same page as the interviewer asked something which I said 15 mins ago in a different context and tried connecting it. It would have been smooth if there a white board. It was difficult for me to talk to interviewer and write something on my note at the same time.

Contact Hr for this role, pass the first HR screen, and was asked SQL and product for the next round. Each part took around 20-25 mins. use SQL to join one table with customer info and fraud
