Hobby questions can be precarious and you want to consider what you will say before going into an interview. Most hiring managers and HR personnel like to hear about active hobbies, like walking, gardening, running, travel, etc., volunteerism, and interesting hobbies like woodworking or aviation. Reading materials can also be nice to include, but stay away from political, religious, romance or science fiction related materials, and instead talk about business related, motivational-type books, doing crossword puzzles or Sudoku. Avoid talking about watching lots of television or spending lots of time at home in general. The more active you show your mind and body to be, the more the interviewer will see you as an active and engaged person for their team. To your job search and interview success!
