Interview Prompt
Since we acquired a hotel chain, its reservation system and ours both take live bookings: about 200 inventory changes a second across 1,500 hotels, 400 of them sold through both. The head of operations wants you to design the pipeline that turns both systems' changes into one inventory picture, with a history revenue management can audit.
Summary
Two systems, two schemas. One truth.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
