Now I also uploaded my PDF resume, not USAJOBS built resume. I am not sure which portion is more important in resume.
Work Experience: now around 60% of page, no more than 4 lines for each agency I work for. It used to be more than 2 pages with detailed job description. This is the main portion I remove from USAJOBS resume.
Skills: 3 lines, only with keywords, rewritten from original half page of USAJOBS Additional Information portion.
Education/Job Related Training(Certificates): 3/4 page.
Professional organization and affiliations(professional related): I don't have active membership anymore, do I still need to keep it in my resume.
Availability portion in USAJOBS resume: completely removed.
