Give me an example of a time when you went above and beyond.

"Last week I noticed that my manager had not completed the schedule for the following week. Some of the staff were complaining that they didn't have their work schedule yet. Rather than going to my manager with the complaint, I offered to take on some of her workload so that she would have the time to complete the schedule. We worked together for a couple of overtime hours that day and were able to catch her up on everything. It felt good to help but also benefited me by way of organization."

"I often go above and beyond what is expected of me. Most recently, I agreed to cover for a co-worker who was on short-term medical leave. I worked 10 hour days for two weeks so that our productivity did not suffer."
