Future worry-free delivery is an unmodified resume, because the first delivery has been successful. When the mistakes in your resume are serious, you need to resubmit it and explain the reasons. If the error is small, you can wait until the company interview to give HR the necessary explanation, and the three types of resume delivery are useless. One is blind worship. Blind worship of well-known enterprises or hot jobs. Well-known enterprises such as multinational corporations are always shrouded in a halo, and they are the employers that graduates dream of. Some graduates blindly submit resumes regardless of whether their major and career direction match the recruitment needs of famous enterprises. In fact, companies like ibm and Microsoft are often the lucky ones who are hired. No matter what their own conditions are, the application is futile.
