It's also the same with "beauty". Even industries that hire primarily based on beauty (modeling, acting etc) have widely differing criteria based on their own niche in the marketplace. American models are quite different to British models, for e.g. The French magazines require a different look to, say, German magazines. Catalogue models vs editorial models. Throughout Europe, various markets require different heights, different looks and different personas. That doesn't even take into account racial differences across the world.
