Perhaps spend some time on a real-world toy problem, the kind where you spend a lot of time dealing with small practical things like error handling? I have interviewed a lot of people for coding jobs, and I usually try to test ability at doing things like this, and when I find someone junior who already knows how to approach problems like this, I am always very in favor of hiring them. Based on the discussion here I'm definitely not the only one.
