Google E-Commerce Product Manager interview questions

Once my session was scheduled, I was interviewed by current product manager from the company. I was asked the question “ What would be a service that you would suggest that Google creates for the world five years from now?“ I was a bit surprised by this question, because materials that I was given didn’t prepare me for it. The person who was interviewing me seem to be in a large room, so I heard lots of noise, like static.
