求职信要发挥最大的效果，语气必须肯定、自信、有创意而不过分夸张，如能事先了解雇主的喜好，或其他人格特点，根据人以群分的原理，求职信如果能迎合雇主的特点，求职的人一定可以比其他人占上风，获得面谈的机会。

注意下面句子中语气的不同：

I think that I would make a good ***** for you. 我想我可能成为贵公司的优秀员工。

I am confident that my experience and references will show you that I can fulfill the particular requirements of your ***** position. 我相信我的经验和别人对我的推荐可以使您充分了解我符合贵公司*****一职的需要。

I recently completed a course in filing at the ***** School of Business. I am competent not only in installing a filing system that will fulfill the needs of your organization, but I am also well qualified to operate it efficiently. 最近我在***********读完*******课程，我相信不仅可以设计一套符合您的要求档案分类系统，而且可以进行有效的操作。

I feel quite certain that as a result of the course in filing which I completed at the ******** School of Business, I can install and efficiently operate a filing system for your organization. 我相信经过我在*******学校的********课程学习之后，我能够替贵公司设置并且操作一套档案分类系统。

第一句显得语气太弱，写信的人有点羞怯的样子。第二句有特殊风格，第三句则太过自信，第四句，作者在表示谦虚。在实际运用中，如果你不太了解雇主的话，不卑不亢比较好。
