As part of the fun and active Google workplace culture, it is important to know that the staff members at Google are referred to as 'Googlers.' By tossing this question your way, your interviewer wants to hear you speak with passion and conviction about what you are most looking forward to in being employed by Google. You obviously have the chance here to take your answer any way that you want, so don't hesitate to be creative. If you feel you've done a good enough job discussing your qualifications for the role you are interviewing for, don't hesitate to talk about the Google commitments or crazy culture and way of life at Google. If you feel you need to reiterate your skillset further for your interview, you can take your answer in that direction as well. No matter how you answer, be sure that your interviewer fully sees the excitement you have about this opportunity with Google.
