求職信是用來向某一單位求取一份工作的信函，它屬于廣義的申請信的一種。之所以將求職信與其他類型的申請信分開來寫，是因為其目前應用的普遍性和重要性，因此希望考生給予足夠的重視。
寫求職信時，要注意以下幾點：
首先，措辭要禮貌，對求職單位要加以一定的褒揚，并表示對該單位的向往之情，希望能到該單位工作。
第二，簡潔、明了、具體地說明自己的能力和條件。因為求職信通常是跟簡歷一起寄給用人單位的，所以在信中提到自己的能力和條件時，不是要簡單重復簡歷中已有的內容，而是要用簡潔、明了、具體的語言提出自己特別突出的或者可能引起用人單位特別的注意的能力和條件。
第三，對于要求取的工作崗位，要特別寫明，給用人單位一個考慮選擇的機會。
第四，要突出招聘者的利益，不要一味強調自己的需要和期望。
求職信一般分為三個部分來寫，至于分成幾段，沒有嚴格的要求。第一部分說明從哪里得到的關于這份工作的信息，又或者寫信人只是投求職信碰碰運氣。
第二部分主要是推銷自己，表達自己對應聘職位的興趣以及介紹自己的最突出的能力和條件。如果求職者對應聘職位沒有太多的了解，可以特別表達一向愿意接受新挑戰的愿望，并強調一下自己在適應新環境、處理人際關系方面的能力。
最后一部分當然是表達一下希望，例如希望能得到面試的機會。
下面給出一封齊頭式的求職信，省略了信頭和信內地址，從稱呼開始。
Dear Sir or Madam:
I am writing in response to the advertisement you placed in the Sunday paper for a sales manager in your company. Your company has a reputation for producing high-quality products like Mandolin network system. I am interested in joining such a professional organization.
As you can see from the enclosed resume, my previous work in an export company has provided me with lots of opportunities to contact all kinds of customers and suppliers home and abroad. By communicating with them, I have got very familiar with the international trade and the current market. Besides, my educational training at university concentrated also on international trade which equipped me with a solid foundation in sales and trade.
As such, I believe that my service could be of great benefit to your company in terms of customer relation and new business connections.
I hope to have an opportunity to meet your human resource manager in order to let you know more about me. I enclose a resume and could be available for an interview at your convenience. Looking forward to hearing from you and thank you for your consideration.
Sincerely yours,
J.S. Wu
