Suppose I have two technologies that are relevant, foo and bar and that I'm weak on bar, so seek to hire someone with bar expertise. If I'm constrained to hire the very first person with more bar expertise than my least bar-skilled interviewer, I probably won't make much progress towards my goal.

The goal is not to hire the first "not worst", but rather the reasonably best, where reasonable is a function of time and money, among others.
