Design a multi-tenant content delivery system that handles millions of requests. Discuss trade-offs in consistency, availability, and performance.

Morgan Stanley asks this during the Onsite to assess your depth in software engineering. They want to see understanding of design patterns, system architecture, and the trade-offs involved in different technical approaches.

What the Interviewer Expects
  • Apply engineering principles to a realistic design scenario
  • Discuss trade-offs between different approaches with concrete examples
  • Demonstrate understanding of testability, maintainability, and extensibility
  • Connect theoretical concepts to production engineering practices
  • Discuss how the approach scales with team and codebase size
Key Topics to Cover
Version control and branching strategies
Performance optimization
System observability and debugging
Testing strategies (unit, integration, e2e)
Concurrency and thread safety
How to Approach This
  1. Apply SOLID principles. Single Responsibility makes code testable, Open/Closed makes it extensible.
  2. Choose data structures based on access patterns, not familiarity.
  3. Prefer immutable data and message passing over shared mutable state for concurrency.
  4. Design APIs with RESTful conventions, versioning, meaningful errors, and pagination from day one.
Possible Follow-up Questions
  • How would you measure the performance of this component in production?
  • What testing strategy would you use for this component?
  • How would this design change if the team size doubled?
