Dear Sir,
In reply to your advertisement in regarding a vacancy in your office, I wish to apply for the position of senior clerk, which you have specified.
I feel confident that I can meet your special requirements indicating that the candidate must have a high command of English, for I graduated from the English Language Department of xx University three years ago.
In addition to my study of English while in the university, I have worked for three years as secretary in the firm of ABC Trading Co, Ltd.
The main reason for changing my employments is to gain more experience with a superior trading company like yours. I believe that my education and experience will prove useful for work in your office.
I am enclosing my personal history, certificate of graduation and letter of recommendation from the president of the university, I shall be obliged if you will give me a personal interview at your convenience.
Very truly yours,
Wan Long
