Interviewers may ask this question in an effort to determine how you have dealt with stress and unexpected events. It is not important to go into the particulars of the emergency, just how you dealt with the situation. If any emergencies occurred, try to show how you minimized the impact on your work. Describe the organizational skills involved in rescheduling and establishing necessary priorities, and how you notified your bosses, and contacted coworkers to cover for you where possible. Convey that you took into consideration those with whom you work and those you report to. Explain that you didn’t take off any more time than was necessary to deal with the emergencies, and stayed in contact with staff and management during your absence to make sure deadlines would still be met, questions got answered, and that you did everything possible so that workloads would be minimally impacted. Also mention that upon your return you got back up to speed as fast as possible to not further impact your work or department or have your personal situation become a distraction to others.
