How does repeating the same tasks every day for 20 years make someone a better software engineer? There are better and worse candidates in either camp. I developed software professionally for about two years before graduated. Is it 20 years? Nope. Conversely, it's more experience than many college grads. Working with super talented individuals with an express focus of learning/improving also gave me a hell of a lot more than "a fresh recollection of algorithms."
