Skill Matching	May require upskilling and training	Candidates often bring ready-to-use skills
Speed of Hiring	Faster, as candidates are already within the organization	Slower due to job postings, screening, and onboarding
Talent Pool	Limited to existing employees	A wider range of candidates with diverse skills

Choosing between internal and external recruitment depends on the role, the urgency of hiring, and the skills your workforce needs to stay competitive. Internal recruitment supports faster hiring and stronger retention. External recruitment expands your talent pool and brings in new capabilities.

Many large enterprises benefit most from a blended strategy that uses both approaches to build a high performing and agile workforce.

FAQs
