A cover letter is a concise written document typically submitted alongside a job application or resume. It serves as an introduction and provides additional context about the applicant's qualifications, experience, and motivation for applying to a specific job position or company. 

The primary purpose of a cover letter is to persuade potential employers to review the applicant's resume and, ultimately, invite them for an interview.

Wondering how to write a Cover Letter in Vietnamese effectively? You only need to follow some fundamental principles:

Personal Information

In this section, you need to clearly state your full name, address, phone number, email, and the date of writing. Additionally, you should provide the company's name, address, and the recipient's name (if known). If you're unsure of the recipient's name, you can generally address it to "Dear Recruitment Committee" or "Dear Company."


When starting your Cover Letter, begin by introducing yourself, mentioning where you learned about the job opening, and summarizing why you wish to apply. You should also clearly state the position you're applying for and show respect and enthusiasm for the opportunity.

For example:

"Dear Company,

I am Nguyen Van A, currently a senior student majoring in Economics at University B. I am very interested in the Sales Staff position that your company is recruiting on website C. With my experience, skills, and passion, I believe I can be a potential candidate for this position."


This is the main part of the Cover Letter, where you introduce details about yourself, your experience, skills, and achievements related to the position you are applying for. You should select the most important information, as there is no need to list everything you have done.

In addition, you should also provide specific examples to illustrate your strengths. Pay attention to conforming to the employer's requirements and expectations and avoid writing too arrogantly or modestly.


This is the final part of the Cover Letter, where you will summarize your main points, express your desire to interview and work for the company, and thank the employer for taking the time to review your application and profile. Use a polite and respectful closing sentence.
