I think the point is that big corporations don't believe in the value and depth of talent. They're not trying to find the world's top software engineers; they just want to find enough good engineers to fill their quota. What that means is that they don't care about depth. They don't care if the candidate is a genius in their domain; they just want to hire people who can reliably solve coding problems; that's it. It's quantitative, not qualitative; it's not about how well the candidate can solve problems - The 'if' is much more important to them than the 'how'. Unfortunately, not many people have the ability to objectively measure the quality of a technical solution, that's why they don't bother at all with the 'how'.
