Side projects. Show me what you've done, and run me through how you developed it. Since you developed it, you should know the inner workings of it.
I love developing it was the best career move i've ever made, but you know what? I also love friends, hiking, jogging, going to the gym, video games, playing guitar, and watching movies.
I don't live to work. I work to pay for the stuff I like to do outside of work.
