When preparing for interviews, fraud examiners should avoid scripting detailed questions. Instead, they prepare notes of key points to cover.

From the Fraud Examiners Manual:

“Whenever possible, do not prepare a list of predetermined questions to ask the subject. The interview should flow freely. The interviewer might, however, want to develop a list of key points to cover during the interview”.

Therefore, the best preparation method is to note key points instead of detailed questions.
