Market Sizing & Revenue Diagnostics | Google Interview Question

Quick Overview

Product / Decision-Making Onsite: Multi‑Part Case and Behavioral

Context: You are interviewing for a Product Manager role. Provide structured, assumptions-driven answers. State any assumptions, show your math, and explain tradeoffs.

1) Estimation: YouTube Cat Video Views

Estimate the cumulative view count for a typical YouTube video about cats uploaded last Friday.

Assume “last Friday” means roughly one week of traction.
If information like channel size or promotion isn’t given, define reasonable assumptions (e.g., small vs. mid-sized vs. large channel) and provide a range.

2) Estimation: Netflix Total Revenue (Last Year)

Estimate Netflix’s total revenue for the most recent full fiscal year.

You may use a build-up model (subscribers × ARPU × 12) and/or triangulate with public ballparks.
Show sensitivity/ranges and sanity checks.

3) Strategy: U.S. vs. International Revenue Drivers

Compare U.S. and international revenue drivers and discuss how those differences should influence Netflix’s strategy.

Consider subscriber growth vs. ARPU, pricing power, churn, content preferences, payments, partnerships, and regulation.
Provide concrete strategic recommendations by region.

4) Behavioral: End‑to‑End Project Walkthrough

Walk me through an end-to-end product initiative you led: the problem, hypothesis, user research, success metrics, roadmap decisions, launch, and post‑launch learnings.

Be concise but specific (scope, timeline, team, results). Highlight decision points and tradeoffs.
