Perhaps your interview process is suboptimized for finding talent.

Google famously struggled with this issue. They found the best predictor of how someone will perform in a job is a work sample test (29%).

This entails giving candidates a sample piece of work, similar to that which they would do in the job, and assessing their performance at it. Even this can’t predict performance perfectly > http://www.wired.com/2015/04/hire-like-google/
