Workspace: NestJS Difficulty: Hard Time: 90 minutes
A education coordinator allocates places across several courseCohorts to continue safely after a partial service failure. The supplied API may succeed for one row and fail or replay another. The current NestJS implementation rolls back shared state and can apply the same intent twice.
CourseCohort 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.
