Applied online - took around a month end to end. Recruiter screen was straightforward: background, motivation, and high-level product philosophy. Phone screen was with a PM - talked about how I’d improve Google Maps for advertisers and estimate YouTube’s storage cost. Onsite loop was 5 rounds: 2 product design, 1 analytical, 1 technical system design, and 1 behavioral. Expect heavy focus on structure and communication. They really dig into how you think, not what you know. Prepped through mock interviews on Prepfully - practiced with a former Google PM who helped me structure product answers better and think more “user-first.” Highly recommend doing at least 2-3 mocks before the onsite.
