Workspace: Fastify Difficulty: Hard Time: 90 minutes
A device lab coordinator allocates units across several testDevices to continue safely after a partial service failure. The supplied API may succeed for one row and fail or replay another. The current Fastify implementation rolls back shared state and can apply the same intent twice.
TestDevice Recovery Allocation 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 hard 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.
