Looking at someone's code is more useful than asking if they know patterns. But some knowledge of patterns is a good thing IMHO.

For example, if I can point at some of my code and say "Yeah, that's kind of like a factory" and know I'm understood by my teammate, then that's a good thing.

One goal of the design patterns movement was to introduce a terminology that could be shared and understood. I think they succeeded to some degree, because employers are looking for familiarity with this terminology. Why is it such a PITA?

But wouldn't it be quite cool if you could check your thinking against other peoples successes and failures? Patterns simply catalogue problem/solution, I don't think you're supposed to implement them in a paint by numbers fashion.
