This question is one of interest, and your response will give the interviewer a good idea of the types of topics in which you like to immerse yourself. The wrong answer to this question is that you don't enjoy reading, or that you aren't reading anything at the moment! A great journalist is ever-curious, loves to learn, and perform research. Discuss the book you are reading and, if you'd like to start a good conversation with the interviewer, you could also ask what book they are diving into currently. Reading recommendations are always a great topic of discussion!
"Right now, I am reading 'Bunk' by Kevin Young. Have you heard of it? The book addresses the rise of fake news, plagiarism, and hoaxes in media and publications today. It's been an informative and eye-opening read. I try to pick up a new book every couple of weeks. Do you have any favorite books you'd like to recommend?"
"This year I committed to reading one new book every week. This week, I am reading 'Evicted' by Matthew Desmond. It dives into poverty in America which is a topic that I have always found fascinating. The gap between the rich and the poor, and what our country can do to help others flourish. I'd love to hear your recommendations if you have some for me!"
