That’s baloney, fella. It’s a privilege to be interviewed by you? It’s an honor for you to make time in your busy schedule to grace the interviewee with your presence?
It would take you a few moments to prepare for the interview; it would also be a nice way of demonstrating respect for the person you’re interviewing. You don’t have to spend “2 hours” on each candidate, but a few minutes more than the 10 you need to study a resumé is warranted!
If everyone at Google is like you, it’s not surprising they have such a lousy reputation for hiring.
