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.
