Multiple choiceMediumchapter-3-curatedpremiumcore-collectionssorting-and-grouping
Answer and explanation
Correct answer
A. Sort or group data in the way that serves the report, reconciliation, or batching decision the operator needs.
Why
Sort or group data in the way that serves the report, reconciliation, or batching decision the operator needs. That is the stronger engineering move because interviewers care whether you can connect the data transformation to a real use case. Performing extra sorting or grouping without a reason adds cost and cognitive noise.
