Baker, a Certified Fraud Examiner (CFE).

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 alist of key points to coverduring the interview”.

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