Interviewers try to understand if you can prioritize your tasks, and work on more things simultaneously, which is a useful quality for any administrative assistant.
You should convince them that you know how to distinguish the important tasks from those that can wait, and that you have decent time management skills.
The best way to do it talking about practical situation from the past, showing them that you did not panic, even if the workload was heavy. Let’s have a look at some good answers.
I do not believe in multitasking, at least not in a true sense of a word. Human brain is capable of focusing on one thing only at any given moment. Of course we can brush our teeth and think about something else at the same time, but that’s possible only because teeth-cleaning is an automated process, something we do without thinking. When I had to handle more tasks at the same time, I always tried to focus on those tasks I couldn’t handle without thinking about them, such as answering phone calls. And while focusing on them, I took care of things such as organizing my table, making coffee, typewriting, etc, since I could do them without thinking.
I have always worked on my time management skills, trying to learn how to organize my day in work. I have a good skill in doing that, so it rarely happens to me that I need to take care of two different tasks at the same time. I always prioritize my tasks in the morning, consult the schedule with my superior, and work according to the plan during the day.
