Mainly consider what the first person who looks at your resume-the position of human resources in various companies thinks. To be honest, you don't necessarily need a letter of recommendation. If a letter of recommendation can outline your own advantages and ideas, then add your job intention and what you can accept. This will help the other person easily sift through thousands of resumes.

But because the resume itself can be downloaded and printed directly from the recruitment website, your situation is clear at a glance, so you don't have to have a cover letter.
