I applied through an employee referral. The process took 3 weeks. I interviewed at Meta (Tel Aviv) in May 2020
Interview
HR sent me a mail asking to descibe my experience, my skills and some additionnals informations.
After, we scheduled a call. Asked me some questions and planed the technical interview. Sent a mail to help to prepare it the best way.
During the technical interview , we used a whiteboard by visio
After some day, I received the response (I would prefer it to be more explained but I knew I failed the interview)
Interview questions [3]
Question 1
Given a table of date, user_id, stuatus_id, action (like, comment, viewm, report) and extra (absurd, violent...) , provide the number of different reports from yesterday.
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

Meta’s evaluation rubrics focus heavily on "Product Thinking over Fancy Math". Interviewers want to see if you can operate like a product owner with an analytical mindset, navigating messy scenarios affecting billions of users

First Tech Screening round - 45 mins (usually can extend a bit depending on the interviewer)
- 2 SQL Questions ( Medium to Hard ) - based on Joins
Full Loop - 4 rounds 45 mins each.
- SQL
- Behavioral
- Analytical Execution - stats & prob, A/B testing, case study
- Analytical Reasoning - Case study

Question 1
Questions on Bayes Theorem, Probability distribution, etc.
