Interview Prompt

We're an e-commerce company like Amazon. When a customer orders a product, it moves through several stages: we purchase it from a vendor, it ships to one of our fulfillment centers, gets picked and packed, then delivered to the customer. Operations needs to see where every unit is at any point. Can you design the data model?

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your data modeling solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
