Practice interviews

1. Can this pipeline replay without changing the count?The retry is a delivery, not another event
2. Would you merge this AI-written field migration?The new field has the same type. Does it mean the same thing?
3. Does a green latest partition prove the dataset is complete?Fresh data can still be incomplete
4. Can an old update restore a deleted account?An old update must not undo a newer deletion
5. Both pipelines agree. Can both publish?Two matching pipelines still need one publishing owner
