The purpose of this question is to check your adaptability and flexibility. Did you feel victimized?

Answer this question by mentioning the change that was made but the main focus should be on how you adjusted in that situation and the results you achieved afterwards.

For example you can say something like, “Being an early joiner in the marketing team, I opened a lot of new customer accounts. Over the time the team grew and we had more people in the team opening more accounts.

This re-distribution meant loss of my high performing accounts and a requirement to develop new accounts in the assigned territory. Initially, it looked difficult but I could understand the need for this re-distribution and saw more opportunities for the company and myself. I introduced my colleagues to the old accounts I held and started strategizing for better ways to tap the new territory. Within 6 months, I could develop 50 new accounts with the help of new strategy. Usually we would achieve this result in 9 months to a year.”
