HR reads thousands of resumes every day, and each resume takes more than ten or even a few seconds. A cover may waste him a few seconds and make HR feel very unhappy and waste time.
What employers value most is whether your resume content is what their unit needs. After all, this is not a draft, so the cover feels redundant.
It's not that the cover of a resume is useless. It depends on the company you apply for. If you are applying for an advertising company or a design company, sending a resume to such a company will make the other party feel that you are very creative.
Resumes should be aimed at different types of units and highlight their professional expertise in resumes.
Some employers may pay more attention to practical experience, so they should highlight practice and put it in a conspicuous position. Some employers may attach importance to the professional foundation, academic performance and other certificates of job seekers, which should be highlighted in their resumes.
