How would you accelerate the response time of a website you created for us here at Google?

When conducting an interview, hiring managers like the ones at Google are interested in one of three things - how you can help their organization make money, save money, or save time. The questions they ask will be specific to these objectives. You can prepare for the interview by understanding the organization's mission, the role of the job you are interviewing for, and how you can help them achieve one of these three objectives. In this case, the interviewer is seeking to understand how you can save time.
