When I was younger, my mother worked as a freight forwarder. After she'd been there for awhile, the company paid to send her for training and certification to work with hazardous materials. If I recall correctly, she signed a contract agreeing to repay the costs of the courses if she left the company before a certain period of time had passed.
Essentially, rather than hiring externally a freight forwarder who is already certified to handle dangerous goods, they identified their strongest existing employee without that certification and paid for them to learn what they needed for a more advanced position, with conditions to assure they recoup their investment. The way I read it, I thought the person you replied to was suggesting identifying existing employees with potential and paying to expand their skillsets for a different role, e.g. with bootcamps or MOOCs, not hiring fresh graduates for low pay.
