Workspace: Express + React Difficulty: Hard Time: 120 minutes
A education coordinator allocates places across several courseCohorts to coordinate daily work while capacity changes. The supplied API may succeed for one row and fail or replay another. The current Express + React implementation rolls back shared state and can apply the same intent twice.
CourseCohort Operations 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.
