What are the "all things equal" here, though? I would tend to disagree that someone who can complete the coding challenge faster is the objectively better candidate. Especially if we are talking about leet coding, where there are people who study their asses off and memorize the common leet code problems. Or maybe the coding challenge isn't leet code, but just so happens to be something that the candidate has done before, or has done recently. Just because one candidate lucked out and has done this very specific thing, doesn't mean they are better than a candidate who could figure it out in half a day, if given a little more time to do so. |

The interviewer and the hiring company does not have a God's eye view of the candidate and must work within the limitations of the hiring process. The best one can do (without resorting to metaphysical processes) is to make a decision that has the highest expected value (or highest chance of hiring a good candidate).
The fact that there could be a candidate that lucked out because they were prepared for the specific set of questions you asked is not specific to live coding problems. You could have asked them anything and they could have lucked out and just happened to be prepared for the answer you were expecting.
That said, I can tell you for certain that if given a task that the average candidate takes 10 minutes, and a candidate completes it in half a day, you're looking at a 0.1x developer right there. That's by definition.
