I applied through an employee referral. The process took 2 weeks. I interviewed at Meta (Tel Aviv-Yafo) in Jun 2016
Interview
All around nice people and HR was excellent! At every stage they were clear and transparent.
Round 1: phone screening with basic logic questions. Checking that I knew basic probability, dependant and independant, stats concepts. Total time was 15-20 minutes.
Round 2: in-person 1:1. Product analytics case study. If we were to add X feature to Facebook, how would you measure if it was a good idea or not? A discussion ensued with each step leading to the next. Total time was an hour.
Round 3: a series of 1:1 interviews over the course of a day. Some in person, some video conf. Two case studies like above, 1 math (mostly probability and stat concepts), 1 SQL analysis, 1 SQL ETL.
I did not get an offer. HR did call me afterwards and reviewed the feedback from each interview. Super nice folk and I'm ok with their setting a very high bar to enter. Was told that I could check back next year.
Interview questions [3]
Question 1
In Mexico, if you take the mean and the median age, which one will be higher and why?
Given a table that each day shows who was active in the system and a table that tracks ongoing user status, write a procedure that will take each day's active table and pass it into the ongoing daily tracking table.
Possible states are:
* user stayed (yesterday yes, today yes)
* user churned (yesterday yes, today no)
* user revived (yesterday no, today yes)
* user new (yesterday null, today yes)
Note: you'll want to spot and account for the undefined state.
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

Question 1
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
The Interview Process is very structured -
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
Interview questions [1]
Question 1
Questions on Bayes Theorem, Probability distribution, etc.
