The difference between interim & recruitment is not clear for most people: they both help organizations find talent, but they serve different hiring needs. An interim agency provides temporary, contract, or project-based professionals for short-term assignments, while a recruitment agency focuses on sourcing and hiring candidates for permanent or long-term positions.
The main difference is that interim agencies supply flexible workforce solutions for immediate business needs, whereas recruitment agencies help companies find employees who will join the organization on a permanent basis.
