求職者向用人單位發出的求職信中，大部分都是應征特定職位的求職信，這一類信通常都附有簡歷，不需要向招聘單位再索取報名表格。
應征特定職位的求職信具有向招聘者說明簡歷和具體求職內容的作用。在簡歷中你已經將自己的職業經歷或教育情況列表說明了，在求職信里就應著重顯示自己的優點。
在求職信里要簡短地對簡歷中提到的與應聘職位有關的職業經歷和技能加以說明。但是，只是簡單的重復簡歷里的內容是不夠的。要把簡歷里沒有的內容充分添加進去，顯示出與其他應聘者的差別。你需要傳達的信息是：對這份工作的渴望，為什么你適合這個職位，以及表達你真誠希望加入對方團隊的愿望。
在第一段里，明確陳述你想應聘的職位名稱，第二段說明你已了解這項工作和公司的要求，闡述你為什么認為你符合對方的招聘條件。第三段講清你本人希望在何時面試、何時可以上班以及其他福利方面你希望的標準。第四段則用表達真誠希望的語句結束這封信。
典型的求職信格式是：你的地址寫在信紙的右上方，地址下面是寫信日期。信紙左上角要寫上接受你求職信的人的姓名和尊稱其下面是該公司的名稱和地址。再下面就是招聘廣告中給出的其他相關代碼。請看如下范例：

Dear Sir,
In reply to your advertisement in Beijing Youth Daily of December 25, I am writing to apply for the position of computer engineer.
I am thirty two years old and a graduate of Beijing Foreign Studies University. My experience in this line of work includes five years as a computer engineer with Shanghai Flash Network Company. I did an excellent job there, and was the Outstanding Employee of 2002-2003 in SFN. The reason for leaving my present employer is because they're closing their office. As for the pleasant and cooperative personality you required: I am very enthusiastic, a good team worker, and I can work both long hours and under pressure.
I am enclosing my resume complete with a recent photo. Should you have any questions, feel free to contact me. Concerning the salary, I would be glad to start with 5,000 RMB per month （after tax subtraction）.
I am eager to become a member of your company’s team and would like to start on the new job as soon as possible. I would be glad to come in for an interview and introduce myself in person.
Sincerely,
Michael Fang
