It will be very difficult for this to scale. Yes, if you are small startup, it is possible. But imagine companies like Google, Microsoft, Facebook, Adobe, Cisco etc with over 1,000 positions per month. Add cost overrun. Add team members taking time out of their regular work to manage the temporary projects. And plus, this model will not work if the candidate is currently working elsewhere. Great concept but not practical if you are large company.
