Small-scale companies are probably more likely to have shapes for hard-to-find people. If you can hire one person to do three jobs you need 1/3rd of a person for, that's more valuable than finding three people who can do that; especially if those three people would have needed to be in close communications with each other.

Big companies tend not to have as many places where they need one person to wear many hats; so their hard-to-finds will tend to be finding deep experts, but there's probably not a lot of positions that really need that.
