求職信要發揮最大的效果，語氣必須肯定、自信、有創意而不過分誇張，如能事先了解僱主的喜好，或其他人格特點，根據人以羣分的原理，求職信如果能迎合僱主的特點，求職的人一定可以比其他人佔上風，獲得面談的機會。
注意下面句子中語氣的不同：
I think that I would make a good ** for you. 我想我可能成爲貴公司的優秀員工。
I am confident that my experience and references will show you that I can fulfill the particular requirements of your ** position. 我相信我的經驗和別人對我的推薦可以使您充分了解我符合貴公司**一職的.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**讀完**課程，我相信不僅可以設計一套符合您的要求檔案分類系統，而且可以進行有效的操作。
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. 我相信經過我在**學校的**課程學習之後，我能夠替貴公司設置並且操作一套檔案分類系統。
第一句顯得語氣太弱，寫信的人有點羞怯的樣子。第二句有特殊風格，第三句則太過自信，第四句，作者在表示謙虛。在實際運用中，如果你不太瞭解僱主的話，不卑不亢比較好。
