I love the "Do you have any questions for me?" line. I use it because I'm lazy and in reality I can read anyone I'm interviewing in five minutes so I just need to waste 25 more minutes. My success record for these quick reads - 100%.

As someone being interviewed, I interpret this as "I don't know what I really want in a new hire, so I'll see what shit will stick when I throw it against the wall." I know that you've seen my resume. You know I have 15 years of experience and am exactly what you need, otherwise I wouldn't be talking to you. The interviewer needs to convince me to want to leave my job and all the benefits seniority brings. When I'm on the interviewee side of the interview, it's not really me being interviewed.
