Which of the following is NOT a key responsibility of a security guard?

Conducting interviews is not typically considered a key responsibility of a security guard. Security guards primarily focus on maintaining safety and security within a designated area through various proactive measures. Their main tasks include monitoring premises to observe for any unusual activities, patrolling areas to deter potential threats and ensure safety, and reporting incidents to the appropriate authorities when necessary.

While security personnel may engage with individuals as part of their duties—such as asking for identification or providing directions—formal interviewing is generally outside their primary functions. Security staff are not usually trained or authorized to conduct interviews in the same manner as law enforcement personnel. Therefore, this distinguishes conducting interviews from the foundational responsibilities typically associated with the role of a security guard.
