Meta Data Scientist interview questions

Recruiter call, then a round 1 coding interview, and then the "full loop" with tests of technical skills, analytical execution, analytical reasoning, and behavior, each an hour but able to be scheduled independently from one another with different Meta employees

5 rounds total- started with a recruiter screen, a tech phone screen, and then the virtual onsite loop (analytical reasoning, execution, tech, and behavioral). tbh it felt like regular conversation and not like getting grilled, may be I got good panel of interviewers lol. They even gave hints if i got stuck. A lot of focus on how you think, not just the final answer. Metrics and product impact come up in almost every round. for prep I read the Ace the Data Science Interview book, grinded LC for the sql stuff, and used this Meta DS guide on the Prepfully (esp product analytics + execution) which had really good deep dives on the execution rounds. plus the usual scrolling on blind and reddit.
