An resume should include only the last ten years of experience.
Content of your resume should be selected strategically to support your focus and value proposition. While it is true that readers of your resume will be most interested in your most recent experience, there is often value in including experience further back in your history. Perhaps your early career includes work for well-known, prestigious1 companies. Perhaps you want to document the full scope of your cross-industry experience, much of which occurred in your early career. Perhaps you believe some valuable networking opportunities may come out of your experience 15 or 20 years ago. Or perhaps your most impressive accomplishments2 were in a position you held 12 years ago. In any case, it will be apparent to the reader that your executive career did not suddenly materialize ten years ago so there is little harm and many benefits to summarizing this early experience. Of course, this does not mean that you must give equal page weight to your early career. If you feel early dates will be used to screen you out, subtly leave them out of your early career summary. If some early career positions have more strategic relevance3 than others, give them more emphasis in your summary. Think carefully about the content of your resume. If there is solid reasoning behind your desire to present early experience, than do so.

简历应该只包含近期10年的经验。
简历的内容应该有选择的提供来支持你简历中的重点内容。虽然简历阅读者是对你近期的一份工作最有兴趣，但同样也对更早的一些工作历程有兴趣。可能你更早的一些的工作是在比较有知名度的公司里。可能可以愈加健全你的工作经验。可能你印象最深刻的收获确实是在12年前的工作中得到的虽然对阅读者而言，你十年前的工作经验非常难物化地去理解，但，描述这早期的工作历程并无大碍却可能会有不少好处。当然，这并非说非得要花纸张去说明过去的经验，而应该视状况而定。假如早期的工作经验并无特点，完全可以省去。假如恰恰相反，早期的工作比其他的更要紧，那就要着重描述一下了。必须要花费心思好好想想简历的内容，假如描述早期的工作经验确实非常有必要，那就写吧。
