Product sense question: Design a volunteer product. The key here is to define where you're building it and why (I said within Facebook.com event section), discuss the mission, goal, North Star metric, competitors, industry etc. Then dive into users and prioritize based on reach and impact. Walk through user journey and brainstorm pain points and feature ideas. Discuss which feature you would prioritize based on RICE (reach, impact, eng effort). Discuss how you would measure success. Analytical question: Define the mission, goals and metrics for Instagram Reels and a Video conferencing app like Zoom (I had two of these interviews - they asked me to redo the first one). Follow a similar structure to the product sense question, except the meat of this question will be some solid North Star metrics and counter metrics. They'll also ask a tradeoff question as a follow-up.
