How should an internal auditor decide whether burnout is a job-design problem or a sign to leave the function?

A Reddit source thread about deciding whether repeated frustration comes from weak scoping, weak leadership, or real career mismatch pushed me to tighten my judgment instead of collecting more generic advice. I want the exam-ready version of the issue, framed the way a CIA candidate or practicing internal auditor should reason through it.\n\nSource signal: the original thread was titled 'Tired of internal audit' and raised a practical problem around study execution, control thinking, or career direction. I need a response that converts that signal into a repeatable framework.
