A resume should thoroughly describe the responsibilities of each position.

The absolute most important element of your resume is your value proposition. Your unique ability to solve business problems, meet challenging goals, and produce desired results should be the focus of your executive profile (see above) and this focus should be supported by proof throughout your career. How better to do this than through achievement-oriented, results-focused descriptions of your career history? While employers and recruiters will want to know the scope of your position (number of direct reports, amounts of budgets managed, areas of management authority, etc.) this is most effectively communicated within the context of the challenges you faced, the actions you took, and the results of your actions. "Responsibilities" only tell the reader what you were supposed to do, not what you actually did do. Use powerful, active language to concisely tell the reader the "story" behind your most recent or relevant positions. By documenting your consistent ability to produce results and solve problems you will demonstrate your ability to produce similar results in the future.

简历应该详细描述你所担任职位的职责

简历中及其重要的一部分就是举出你所担任的重要的职位。你解决工作问题的能力，接受挑战的能力以及满足需求并完成任务的能力等等。当然还要把证明拿出来。因为职责只是告诉大家你应该做什么，而不是你实际做了什么。用有力生动积极的语言来简明地说明你最近的职位背后的工作，也就是你的努力。通过描述你为了满足需求的努力和解决的问题就能很好地证明你将来在解决相似问题上的能力。
