Just wanted to put in a plug to say I landed a new job and I fully credit my success in the interviewing process to the interview series. More specifically the recruiter noted that what put me above the rest was my energy and enthusiasm i showed each person I interviewed with.
This is definitely the effect of CLOSING everyone I interviewed with not only in the interview but in the follow up.
One other thing that I would like to pass on. I practiced my answers per the interviewing podcast but one thing I think that really helped in the final set of interviews ( which they flew me up to interview ). I fully engaged my seat mate and instead of worrying about the interview and studying notes, I got to practice off the cuff back and forth with him for an hour. I can't really think of a better way to build confidence and loosen up prior to a series of interviews.
If you have an interview coming up, try and seek out conversation with someone you don't know ( preferably in your industry ) and see if it doesn't help build your confidence and readiness to do it when it counts.
