Product Data Scientist (L5) Interview Experience

I had already been referred and was already in touch with a recruiter (for a previous interview process), so the first loop moved unusually smoothly and I even got to skip the technical screen there. The product loop was more standard: recruiter, a technical screen with SQL plus schema design, then a three-round onsite covering stats/modeling, experimentation/applied analysis, and Googliness. The tricky part is the two analytical onsite rounds overlap a lot, but the stats side was more trivia and mechanics than I expected, while the experimentation side stayed pretty close to standard A/B testing frameworks with a little causal inference mixed in. Overall the interviewers came off very friendly and conversational, and I finished my last onsite in mid-December.
