One thing I have seen is that they lack understanding of how to test things. It's not their fault. Most schools and universities that teach Computer Science often dont focus on this and might have a class on it, but that's it. I find that troubling. When ever we have an intern I take the time to teach them the TDD and how to write good unit tests.
