At what step in the interview process should the investigator begin probing for any competency or credibility issues that might arise?

• A. First step
• B. Third step
• C. Fourth step
• D. Second step

Answer: (D)

Probe for competency and credibility early in the interview, after you have established basic rapport and collected initial information. This timing lets you gauge whether the person can understand and recall events and whether what they report seems trustworthy before you delve into deeper questioning. Checking credibility at this early stage helps you spot inconsistencies, memory gaps, or red flags while the interview is still fresh and you can adjust your line of questioning, rather than waiting until later when you might rely on flawed information or damage rapport by pressing too hard.
