Do you work well under pressure?
The interviewer is revealing that there will be times in this role you will have to handle competing priorities or tasks, and they want to ensure that you can work in these conditions.
This question has a clear right answer. The interviewer is revealing an important need for the business and the team. They want to ensure that you can meet this need.
Answer this question with an affirmative, and be sure to provide examples of times you have had to work under pressure. Be specific as to whether these examples are of competing priorities, a complex task, or another related dilemma.
Avoid telling the interviewer that you are not comfortable under pressure unless working in this manner is a deal-breaker for you. Doing so may just be a deal-breaker for them!
"I'm accustomed to working well under pressure. In my last few roles, I was required to handle inboxes that often had urgent matters, and I am used to having to jump from one project to another, depending on which is more important."
