Workspace: NestJS Difficulty: Medium Time: 60 minutes
A migration engineer searches migrationBatches to continue safely after a partial service failure. Every query uses the supplied local API, and responses may settle in a different order from the requests. The current NestJS implementation can replace the latest result with an older response or error.
MigrationBatch Recovery Search is a coding (platform) interview exercise that trains prompt interpretation, explicit assumptions, a concrete response, and a clear explanation of tradeoffs. The catalog marks it as medium difficulty. It focuses on Technical Reasoning, Testing, Validation. The signed-in workspace provides the tools for the round and evaluates the attempt against task-specific criteria. Reference solutions, hidden checks, evaluator instructions, and candidate work remain private.
