2 Pages is *very* real!
Not true! I have 22 years of IT work experience, and my resume fits neatly into 2 pages.
The thing is, it's not necessary to list all of your experience in a resume. As I mentioned in another post on this thread, the point of a resume is to get you an interview - that's it. A resume is not an autobiography.
What you *can* do with a wealth of history is prepare a bunch of accomplishment bullets pulled from your various successes over the years, and then cherry-pick from those to customize the resume you send for a particular job listing. I categorize mine - "Management focus", "Engineering focus", "Project Management focus", and pull from them as needed.
Each bullet is 2 lines or less, stating what I did, how I did it, and ending with a measurement of the benefit. For example, "Consolidated file servers, decommissioning superfluous systems, reducing support and licensing costs by 20%."
I'll say it again: The purpose of a resume is to get you an interview. It needn't tell your whole story!
