I've been searching for a new job for several months. I have had a couple of offers, but for various reasons, turned them both down. I am 51 yrs old and have given myself the luxory of holding out for a job I will truly enjoy and feel passionate about. I want something I can stay in till retirement and feel good about doing. 
 
Just last week I got a surprise phone call asking me if I'd like to interview for a great job that's just opening up in my area. I had applied for a different job with the same agency several months ago and they'd held onto my resume, which they pulled now. The person who called me was very vague and told me only the position title, that there would be 4 of us interviewing for a single position, that the position was new and covered under a new federal grant, and that I was the first being called. I have done some research and found that the job is one that I feel I would be very good at and would really enjoy. I have shared this with a few close friends and they're telling me too that it seems to have been custom made for me. 
 
I have my interview in a couple of days, so have been gathering facts on the new program, the objectives and goals of the agencies spearheading it, and the more I learn the more I really want this job. Luckily, I have experience in all the areas listed in the information, which is almost comical since some of it is so long ago that there is no mention of some of it on my resume. I want to be able to go in and simply WOW the interviewer with my qualifications and passion for this particular job.  
 
This job involves working with 16 - 21 yr olds who have been incarcerated and are being released. It is helping them to get back into school, preparing and training for jobs, and helping to open some doors that would otherwise be locked to them. I have been doing this on my own for several years without the benefit of any help, so this program sounds like a dream come true.  
 
I realize I have only 1 hour and chance to make a lasting, positive impression on the interviewer. I want to point out what I have told you all here and yet I don't want to come across as a lunatic in the process. Any tips and ideas would be greatly appreciated. I've been prepping myself using the info on the site of the agency I would be interviewing with since they offer tips for successful interviewing and so on. How much is too much and how hard can I press without going too far? 
 
Thanks!
