Solicité el puesto a través de un captador. El proceso duró 2 semanas. Acudí a una entrevista en Meta (Boston, MA) en mar 2018
Entrevista
HR reached out to me on linkedin for data scientist infrastructure position. Scheduled an interview after 2 weeks. This was a technical round with sql, python and statistics questions. The interview lasted for an hour with live coding. The interviewer was very nice and i answered all of the questions. I was not sure about logic for one of the questions on python. Rest were right. I did not make it to the next round. I am sure what went against me but assume python was the issue.

Pregunta 1
A table has a column with full names(e.g. 'Tom Hardin'). write a python code to get distinct first names(i know its super easy in sql)
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.

Pregunta 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
