Summary

PM interview at Google with a product sense question about quick commerce. Not a lot of context to go on from what I remember but it was a pretty meaty question if you haven't thought about that space before.

I'd looked at a few of these apps as a user but never really broken down the operational model.

Suggested Approach

Start by defining the core value proposition of 15-minute delivery and the unique operational model that enables it, then analyze the unit economics and product experience, and finally discuss strategic trade-offs and future sustainability. Structure your answer around the customer problem, the operational engine, and the business viability.

Pro tip: Acknowledge that 15-minute delivery is not just about speed but about creating a new habit of instant gratification, and that the real challenge is balancing customer experience with profitability through dense networks and high order frequency.

1. Define the Value Proposition

Explain what problem 15-minute delivery solves for customers (convenience, immediacy) and how it differentiates from traditional delivery or shopping.

2. Describe the Operational Model

Outline the key components: dark stores (micro-fulfillment centers), hyperlocal inventory, dedicated fleet, and AI-driven demand forecasting and routing.

3. Analyze Unit Economics

Break down revenue streams (delivery fees, markups, memberships, ads) and cost drivers (labor, rent, technology, customer acquisition) to assess profitability.

4. Evaluate Product Experience

Discuss the app's UX, personalization, subscription models, and how it drives retention and order frequency.

5. Assess Strategic Challenges

Consider scalability, regulatory hurdles, competition, and long-term sustainability, including potential pivots or expansions.

Key Points to Mention

Dark store economics: high rent for urban locations but reduced last-mile cost due to proximity.
Batching and routing algorithms to optimize delivery efficiency and reduce cost per order.
Subscription models (e.g., memberships) to increase customer lifetime value and offset delivery costs.
Inventory management: limited SKUs (often 2,000-3,000) focused on high-frequency essentials to reduce waste and improve turnover.
Customer acquisition cost and retention challenges in a competitive landscape.
Regulatory and labor issues: classification of delivery workers, local zoning for dark stores.
