Oftentimes, translations are needed to be wrapped up at a fairly quick pace with no room for error. The interviewer will likely follow-up with a question regarding the average length of each translation you take on and how you feel about your pace. When answering this question, know that the circumstances of each translator are different, so don't share outside of your abilities. Higher volume isn't always impressive in an industry that values quality. If you are early on in your translation career, or you are keeping yourself at a comfortable pace, then consider adding to your answer that you are interested in ultimately scaling up your translations per month to demonstrate your desired growth.
