Front End System Design Interview Checklist

• Ask for clarifying questions
  • What is the scale of the solution needed?
    • How many daily active users?
    • How are they geographically distributed?
    • What are we expecting in terms of peak traffic?
  • What are the most business critical use-cases?
    • What's a user persona we should be targeting?
• Identify constraints
