Diagnose the real question

The central issue is usually this: Preparation must match the interview format and reveal reasoning, not become endless study disconnected from the actual evaluation. Before acting, separate what you know from what you assume. Confirmed feedback, response rates, work samples, compensation details, deadlines, and direct conversations are evidence. Fear, optimism, and conventional wisdom are inputs, but they are not proof.
