The catalog marks it as medium difficulty. It focuses on Debugging, Tradeoffs, Technical Reasoning. 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.
