If you have 1 candidate, it's an easy call, if you have 3 candidates, you evaluate in less than a week. If you have 200 candidates, you need to hire somebody to sift through the resumes, have like 5 rounds on interview and everybody chiming in, whoever pulls the trigger or recommends someone is now on the hook for their performance.
You can't evaluate all the information and make an informed decision, the optimal strategy is to flip a 100 sided die, but no one is going to be on the hook for that.
