ACFE Updated CFE-Investigation Exam Questions and Answers by colby

Best practice is to conduct interviews individually. The Manual states:

“When conducting interviews, witnesses should be interviewed separately. Interviewing multiple witnesses together risks contamination of testimony and reduced reliability of responses”.

The recommended questioning order is:

“As a general rule, questioning should proceed from the general to the specific; that is, it is best to seek general information before seeking details”.

This ensures the respondent provides a free narrative before narrowing down to specifics.

Before conducting surveillance, a memorandum should document the basis for the covert operation, including: (1) the information the operation is based on, (2) expected information to be gained, (3) identities of suspects (subjects) if known, and (4) operatives under the examiner’s control. Confidential sources should not be identified by name but referred to symbolically.

The manual emphasizes that interviews—especially with subjects in other jurisdictions—pose legal and cultural considerations. Fraud examiners must consider cultural norms (such as personal space, body language, and eye contact) and jurisdiction-specific laws governing the use of information from interviews. In particular, some jurisdictions limit how interview information can later be used. Therefore, the most accurate statement is that the examiner should verify such limitations before proceeding.
