Reviewing Your Solution

This section of the system design interview focuses on identifying and evaluating trade-offs within the proposed design. Here's how we navigate this:

  • Start with non-functional requirements: We begin by analyzing how non-functional requirements, such as durability, influence design choices and user experience.
  • Analyze access patterns: We consider how users interact with the system, examining the frequency of different requests and their impact on optimization strategies.
  • Make conscious trade-offs: Based on our analysis, we make deliberate trade-offs, such as potentially sacrificing immediate consistency for faster read operations.
  • Use precise language: We use clear and established engineering terms to facilitate accurate communication and efficient use of interview time.
  • Remain adaptable: We stay open to feedback from the interviewer and adjust our design based on their input, acknowledging their understanding of the system.
