What type of selection involves hiring from existing employees within the organization?

Hiring from existing employees within the organization is referred to as internal selection. This process focuses on utilizing the talent already present in the company, which can help foster employee morale, as staff members see that there are opportunities for advancement within the organization. Internal selection can also be more cost-effective and efficient since current employees are already familiar with the organizational culture and processes.

Additionally, internal selection often leads to better retention rates, as employees who are promoted from within may have a deeper commitment to the company and its values. It recognizes and values the skills and competencies that current employees possess, allowing organizations to leverage their existing workforce while also encouraging professional development and career progression for their employees.

The other options refer to different methods of hiring, focusing on external sources, direct methods of recruitment, or broader recruitment strategies, rather than specifically on filling roles from within the organization.
