According to the article, what is true about hiring managers? ( )

参考解析：

B选项定位原文第四段It's common for employers of recruiters to sort through hundreds, or even thousands, of resumes to fill one position.可知，一个职位可能受到成百上千的简历，B选项说一个职位很难收到简历是错误的。C选项错误，本文就是在说一页纸的黄金法则已经不是必须，而是要视情况而定。D选项定位原文第三段，Your resume is a career marketing tool, not an autobiography. Strive to keep your resume concise and focused on your key selling points.作者认为简历上要简明扼要的说明工作经历，所以D选项错误。A选项定位原文第四段Hiring managers often give resumes just a cursory glance before deciding if the applicant deserves to be added to the "maybe" pile.招聘者通常只看一眼便可以决定这个人是否会被列入候选者行列。故本题正确答案选A。
