Candidatei-me de outra forma. Fui entrevistado pela Meta (Londres, Inglaterra) em jul. de 2019
Entrevista
The first stage is a screening call with a recruiter, then there was an online interview data scientist comprising of two parts - analytical and technical. The analytical part was a case study about a specific new feature and I was asked to give possible metrics and evaluate the feature's performance. The technical part was a SQL type question (which could have been answered also in Python or R). The third part would have been a series of on-site interviews, but I didn't pass the second stage.

I was given two tables of friends and interactions on a plain text environment and asked several questions that required joining, grouping, aggregating and doing some other manipulations on the data to get the answer
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.

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.

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
