If you are a favorite company and think you meet the requirements of the other party, you can write a letter of recommendation, but you must write it according to the specific position of the specific company.

If it is an email resume, it is best to use txt format. If you have a cover letter, you can use the text cover letter+attach a resume.

The standard writing of the email title should be the resume of a position (what position to apply for). You can add a sentence that you think is the biggest highlight, such as five years of working experience in the same industry.
