You can say that you will go the extra mile, but it's best to give a real-life example to the interviewer about a time when you did just that. Offer up your references as well and discuss with the interviewer what you feel your most recent employer would say about you. Give examples of how you go the extra mile in the workplace.
Here are some ways that employees will go the extra mile:
- Starting on an upcoming project ahead of time, without being asked.
- Taking action on any feedback, they receive from their manager. Taking action means attending a class to improve a required skill or reading a self-development book to help with communication skills at work.
- Coming to meetings ready to brainstorm or, better yet, with ideas already jotted down
- Creating new ways for themselves or their team to maximize efficiency
- Going out of their way to make their customers happy
