Interview Prompt
Finance reports the daily orders dashboard is missing roughly 3% of revenue versus the source system of record. Reproduce by running tests/test_late_events.py. Fix the pipeline so the test passes; keep any currently-passing tests green. Be ready to walk an interviewer through what changed and how a re-run on the next hour does or does not double-count.
Summary
The clock was lying.
How This Interview Works
- Read the task and the repository: the files, the failing check and the constraints
- Work the fix with the AI agent at your side, and run the checks until they pass
- Submit, then answer the interviewer's questions about the change you made
- Get a hire or no-hire decision with feedback on how you drove the agent
