It's a maximization problem. The goal is to have the best possible ROC curve for your hiring process. Maximize true positives while minimizing false positives.

My personal threshold attempts to minimize false positives even to the extent that I will pass on people that would probably have done a good job. I tune it this way because I think that bad hires are one of the worst things that can happen to a team. But, each individual has to calibrate this for themselves.

I'm not looking to solve the problem, I'm looking to make the best possible decision based on the information I have available.
