If you could improve your writing style in any way, what area would you focus on?

This question is another way of asking about your weaknesses, as a writer. The interviewer would like to know where you want to improve your work so they know the area in which they would need to train you. Your response will be stronger if you can show that you are already taking action to improve that weakness. That action could include online or local coursework, taking on a writing mentor, or reading more books in the style of which you want to learn.
