Answer:
Internal recruitment
Step-by-step explanation:
Internal recruitment is when a company sources for qualified candidates from its internal workforce instead of from outside the organisation. For example if there is opening for an accountant, the company can advertise internally for all qualified accountants to apply.
Internal recruitment has the advantage of less culture shock and little training on how the organisation functions.
In this instance human resource (HR) department of Wardund, an event management company, sent emails to all the employees of the firm, inviting qualified candidates to apply for the position of business development manager in the company.
