It's not inefficient if your metric is quickly getting workers in the door as contracting firms are built for this purpose. But you could argue that it will result in a poorer selection of high-quality candidates. I'd say this is because when hiring non-technical workers they're incentivised for numbers. This is in contrast to employment consultants getting fees in intervals over a period of a person's time with an employer, usually done for executive positions. So I'd say optimise your agreements with contracting firms for quality rather than quantity by paying them bonuses in intervals, with a low initial payment for the finding the candidate.
