Earning through the peer to peer hiring process is a way to increase the engagement of those who already have found jobs through the platform since they will try and find friends who are looking for jobs and encourage them to use the system.
Employees earning referral fees whenever a friend they referred to the company gets hired is a normal thing. This platform improves that system because you can refer any friend you know to an open job available through the platform, not necessarily your employer.
Many companies are doing that already, especially big companies and BPO companies, since they have a great need for FTEs. Sometimes you refer a friend and your friend gets on a different project or campaign and you don't really get to work together.
