Summary

Short PM screen at Tinder, basically one question about how their product is structured under the hood. Pretty quick but made me realize I hadn't thought carefully enough about the actual API surface of apps I use every day.

Suggested Approach

Start by clarifying that you'll focus on core user-facing endpoints that power Tinder's main features, then name four endpoints and briefly explain the user action each supports. Tie each endpoint to a product capability (e.g., swiping, matching, messaging) to show product sense and technical fluency.

Pro tip: Don't just list endpoints—explain why each exists from a product perspective, and mention that real endpoints would be versioned and secured with authentication. This shows you think like a PM who collaborates with engineers.

1. Clarify scope and assumptions

State that you'll focus on core user-facing RESTful endpoints for the main app, assuming standard authentication and versioning. This sets context and avoids ambiguity.

2. Map core user journeys

Identify the key actions in Tinder: discovering profiles, swiping, matching, and messaging. This ensures your endpoints cover the product's primary value proposition.

3. Name four endpoints with HTTP methods

For each journey, propose a clear endpoint (e.g., GET /recommendations, POST /swipes, GET /matches, POST /messages) and specify the HTTP method and purpose.

4. Explain product rationale

Briefly describe how each endpoint supports a user need or business goal, such as personalization, real-time interaction, or retention.

5. Acknowledge technical considerations

Mention that these endpoints would require authentication, rate limiting, and versioning, and that some actions might use WebSockets for real-time updates.

Key Points to Mention

  • Core user actions: swiping, matching, messaging, profile discovery
  • RESTful conventions: resource-based URLs, HTTP methods (GET, POST, PUT, DELETE)
  • Authentication and security: OAuth tokens, API keys, rate limiting
  • Real-time features: WebSockets or long polling for chat and match notifications
  • Scalability: pagination, caching, and load balancing for high-traffic endpoints
  • Product metrics: how endpoints enable tracking of swipes, matches, and messages
