Which of the following is an external recruitment method?

The correct choice is advertisements in newspapers because this method seeks to attract candidates from outside the organization. External recruitment is crucial for bringing in new talent that can provide fresh perspectives and skills to the company. It involves reaching out to potential applicants who are not already part of the organization, making advertisements in newspapers an effective way to reach a broad audience.

In contrast, the other options focus on internal methods or communication within the organization. Employee newsletters share information primarily with current employees, internal referrals encourage current employees to recommend candidates from their networks, and announcements at staff meetings are typically directed at the existing workforce. These methods rely on leveraging the existing employee base rather than sourcing candidates externally.
