You want to convey that going "above and beyond" is your norm. Communicating how you weigh success is the aim. Break down what success means to you across all fronts; short-term goals, long-term goals, the big picture, and how you achieve your results. It's okay to boast a little when answering this question. Be proud yet humble. Describe how your achievements act as milestones towards your goals in your personal development.

"They needed volunteers for a project that lacked direction and information. I volunteered and expressed to our leadership that I wanted to have a sit down before I embarked on the project to determine not just what their wants but their needs and the trajectory for this project. I worked with them for all the big-picture 'need to know basis' intel on what we were shooting for with this project and why. It took some work to get all the details from them, but once I had all of that, I knew what to shoot for. So that helped me establish a guideline for what I was trying to achieve. If I started wondering what direction I should take with the project, I simply padded the job. As long as I wasn't exhausting company resources, I explored every avenue. Once my tasks were complete, I handed over my work, and it turned out I was so thorough that I'd already completed the work my leadership was responsible for. They were extremely pleased with my work. But that's my standard, to be as consistent as possible in being an above and beyond performer."
