Interview Prompt
Series-B startup, sixty-third night. The company's first nightly pipeline crashed at row 180,000 last night, the orchestrator retried, and revenue inflated 41 percent. The CTO wants this failure mode prevented from ever recurring. Apply the section's four-step synthesis to build the first idempotent DAG so both halves of the two-way contract are present and the dashboard reads from the idempotent path.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your pipeline design solution with real code execution
- Get instant feedback and a hire/no-hire decision
