Interview Prompt

We acquired a hotel chain that runs on a completely different reservation system than ours. Both systems are live and taking bookings, and both change their data constantly. Our operations team needs a single unified view of all inventory across both systems. Design a pipeline to keep that unified view current.

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