Workspace: Spring MVC Difficulty: Hard Time: 90 minutes
A on-call coordinator allocates positions across several onCallShifts to coordinate daily work while capacity changes. The supplied API may succeed for one row and fail or replay another. The current Spring MVC implementation rolls back shared state and can apply the same intent twice.
OnCallShift 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.
