Just wrapped a PM loop at eBay for a senior PM role on the marketplace team. Going to write up the actual questions because PM interview breakdowns for eBay are rare.
Structure: 4 rounds, all virtual. Product sense, analytical, execution, and a cross-functional round.
Product sense round (60 min) Two product design questions: "How would you improve eBay's mobile experience for first-time buyers?" Classic but they pushed deep: who is the first-time buyer, what's their mental model, how is eBay different from Amazon's UX for this audience, what metric are you optimizing for? "eBay is losing market share in electronics. Design a product intervention." Not a feature request, they wanted real diagnosis first. Why are we losing? What does the data say? What's the root cause hypothesis?
Analytical round (60 min) SQL scenario: given tables for listings, transactions, and user sessions, write queries to identify sellers with suspicious activity (sudden volume spike + new account). Moderate SQL complexity. Then: if you had to build a dashboard to monitor seller trust signals, what metrics would you track?
Execution / leadership round (45 min) Pure STAR behavioral. Questions were: Tell me about a time you launched something that underperformed. What did you do? Describe a time you had to say no to a stakeholder. How did you handle the aftermath? How have you worked with engineering when you disagreed on scope?
Cross-functional round (45 min) Scenario: you're launching a new seller protection feature. Walk me through how you align legal, trust & safety, engineering, and the seller community team. This one was about process and communication, not product.
Overall: eBay PM interviews felt less 'framework-y' than Google and more operational than Meta. They want you to think like someone who has to ship in a messy legacy environment. Not greenfield thinking.
