"One of the companies I use to work for was still in the Dark Ages. They could hardly use Excel and had no idea what kind of platforms were available that could help them with their process. They had just recently gone public and only had about a hundred employees, so I went in and helped them improve their systems through training and getting them to use Quickbooks as well as other programs. They quickly caught on and have been thriving ever since."

This is a way of asking if you'd consider improving a process or suggesting an improvement without being asked. It's important as an auditor to help client companies grow and become independent. To accomplish this, auditors are often frequently required to review and improve the processes.

If you haven't done this, admit it rather than fabricate something. This isn't something you generally learn in school so being honest is the best policy. This could be a good place to show problem solving in different way from personal experience.

"When I worked with a client for about three months, I realized they were doing all their calculations manually. I created an Excel spreadsheet to show them how valuable the formulas were and how much time could be saved. They took my suggestion and implemented it, transforming a five-day process to a one-day process by removing all the menial manual work."
