How do you like to spend your spare time?

If your hobbies present conflicts with work, such as saying you have full availability to work any hours so that you have a better chance of landing the job, but then also relay that in your spare time you spending every night performing live with your band until 2am, then your interviewer will doubt the authenticity of your previous answers throughout the interview set. This question can also provide you with an opportunity to make yourself more seem interesting and more relatable. Taking this approach could result in some connective conversation that might leave the interviewer with a more memorable interview experience.
