I see what you're saying. The programming contest winner will do better on the algorithm brainteaser questions, so is more likely to get hired, even if he's lacking the ability to do better after he's hired.

It sounds his conclusion is measuring a defect in their hiring process more than "programming contest winners tend to make worse employees".
