Does Your Resume Have To Be One Page. Keeping your resume to one page gives them time to find work experience and skills that match their requirements. In fact, it's been dead for a while.
If you’ve spent the past 15 years working as a business transformation manager and you have a lot of examples to communicate on your resume, then definitely go with a longer one. You can include additional information on your linkedin profile, online portfolio, or a personal website. A resume should be one page most of the time.
