I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (New York, NY) in Jun 2020
Interview
Be prepared the interviewer may start to eat his lunch when you are talking or answering questions. Highly doubted if it was a part of the interview. If you ask me to evaluate it, I would give a negative experience. I think he did not prepare anything for my interview. He probably did not read my resume at all.
When I started to introduce myself, he interrupted me at the second sentence, so I did not even finish my introduction.
When I was answering his questions about a FB product, he started to eat food in front of the camera... In the last part, after I asked him two questions, he did not give me any useful information, which made me feel that it bothered him very much to answer my questions.

Question 1
How to evaluate the impact for teenagers parents join Facebook
Tough interview overall—definitely not what I expected. The technical rounds were intense, particularly when they had me design an A/B test for the News Feed ranking algorithm. I had to discuss metrics and sample sizes in detail. Lucky for me, the time I spent on PracHub right before the interview helped me nail that deep-dive question as it mirrored what I practiced. The behavioral questions felt standard but were still challenging. After a whirlwind process, they extended an offer, which I happily accepted.

Question 1
Design an A/B test to evaluate a new ranking algorithm for the Facebook News Feed. Walk through metric selection (engagement, time-spent, MSI, well-being), unit of randomization given network effects between friends, sample size and power calculations, how you'd detect novelty effects vs. true lift, and how you'd handle a guardrail metric regressing while the primary metric is up.
Total 7 rounds: first round for resume screening, second for technical screening, then for on-site virtual with 4 interviews back to back, then hiring manager round after team matching and then salary negotiation with HR
