Interview Prompt
The release engineering team is charting deployment velocity from deploy logs whose deploy times are stored as text timestamps, and wants a steady per-week rate rather than raw counts. Show each quarter alongside its average deploys per week, busiest quarters first.
Summary
Thirteen weeks. This is how the team spent them.
