Being able to adapt to change in the workplace is an essential skill to possess because change is inevitable. The interviewer would like to know about a time you were required to adapt to change in the workplace.
Sample answer in my view is to be "In my current management position, it was a lot of change to handle in a short time, especially being unsure of who to report to ahead of others and it took a little while to adjust. The training component of my staff was not easy either. However, in the end, it was worth it to secure such a high profile."
