Example answer — fictional, for practice
Our team needed to replace a database used by an API without disrupting access. I owned the migration plan. I first identified the queries most likely to fail and wrote integration tests for them. I then proposed a staged rollout so we could compare results before switching traffic. The migration completed without an interruption reported by customers. I would improve the next rollout by agreeing on rollback signals earlier.
