To be clear, the cost that you will have to bear by partnering with an RPO agency depends on the services that you want. But going by public opinion, there are enough testimonials out in the open about how clients actually optimised their overall spend and cost by choosing an RPO partner over a traditional recruitment agency, headhunter or an on-site recruitment team. Your requirements will need to be assessed by an RPO partner first who can then tell you how exactly you can optimize your spend.
