In the 2004-2007 timeframe, the company I worked for hired software engineers via a staffing company for three-month contracts. We interviewed the candidates with the intention of making a full-time hire. As the contract term approached, the management team did a 360 review, the decided to offer a full-time position or just not-renew the contract. This had some downsides, but overall I found it to be better that alternate approaches I've tried before or since. It stopped being viable once software engineering became a sellers market.

This seems to work ok for companies working on green field stuff, though you'd still probably struggle to entice people to leave their jobs for you. For other companies though, where technical debt and poor management is everywhere you look it doesn't. It gives employees a chance to see what they're really dealing with and to look for work two months later.
