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.
