This question aims to assess your general attitude towards change in a corporate environment while revealing how you deal with and adapt to change. Policy changes and restructures are a commonality in the growth of a company. Change can be challenging for many. In such situations, it's common for employees to fear such change as a sign of job insecurity. This assumption often leads to a rumor mill and sowing dissent in the workplace, which harms the team's effort and contributes to upheaval and turnover.
Maintain a positive attitude and avoid speaking negatively about any previous employers. You want to come across as a supporting influence for your employer, so offer the course of action you took to understand and support the bigger picture and the end goal. Provide an example of a situation in which you faced such a challenge and were a supportive communicative force for the company's vision.
