TheFraud Examiners Manualspecifies that admission-seeking interviews should only be conducted when:
* "There is a reasonable probability that the respondent has committed the act in question.
* All other reasonable investigative steps have been completed.
* The interviewer can reasonably control the place, time, and subject matter of the interview." There isno requirementthat the examiner must be sure no one else was involved. Therefore,C is correct.

The calibration (or norming) process in interviews is meant to establish a baseline of the subject's normal verbal and nonverbal behavior. This is done by askingnoncritical background questionsso that later deviations can be more reliably identified.
From the CFE Prep guide:
"The proper way an interviewer should start the calibration (norming) of a witness is through the use of:
Noncritical questions on background information.... Examples of noncritical questions include 'When did you start with the company?' and 'How long is your commute?'".
Thus, the correct answer isD. "How many jobs have you had before this one?"since it is a nonthreatening background question.

TheFraud Examiners Manualwarns against phrasing admissions as direct questions using emotive terms:
* "The admission-seeking interview begins with a direct accusation... The accusation should be phrased as though the accused's guilt has already been established. Emotive words such as steal, fraud, and crime should be avoided... Wrong: 'Did you do this?'".
Thus, phrasing the question as"Did you steal the money?"is least effective.
