Example of a good response to this question: When I was working as a customer service representative at XYZ company, I had to quickly adapt to a change in the workplace. The company had recently implemented a new software system to help with customer inquiries, and I had to learn how to navigate it quickly in order to keep up with customer demands.
I was able to use the tutorials provided by the software as well as ask questions to my colleagues to become knowledgeable in the system. I was able to quickly adapt to the change and soon enough I was able to use the system for customer inquiries with ease.
