What is a critical skill for an auditor when completing interviews?

Effective communication is a critical skill for an auditor when completing interviews because it enables the auditor to engage with interviewees in a clear and understandable manner. Good communication skills help the auditor to ask relevant questions, listen attentively to the responses, and clarify any points of confusion. This facilitates a productive dialogue that can uncover important insights regarding the organization's information security practices and compliance with ISO/IEC 27001 standards.

Furthermore, effective communication fosters a trusting environment where interviewees feel comfortable sharing information, which is essential for gathering accurate data. It also allows the auditor to articulate findings and recommendations clearly, ensuring that stakeholders understand the implications of the audit results.

While technical expertise, salesmanship, and crisis management are valuable skills in various contexts, they do not directly contribute as significantly as effective communication does in the context of conducting interviews during an audit. Technical expertise is important for understanding the subject matter, but without the ability to communicate effectively, the knowledge may not be conveyed properly. Salesmanship is more focused on persuading or selling ideas, which is not the primary aim of an audit interview. Crisis management deals with handling unexpected situations rather than facilitating informative discussions during the interviewing process.
