It is best not to send your resume as an attachment. We do human resources work, and generally don't read resumes in the form of attachments. The main reason is: 1. Some viruses will spread in the form of attachments, which will be poisoned when opened, so we generally don't open unknown emails; 2. There are many attachment formats. If the recipient's computer doesn't have the corresponding software, it can't be opened, mainly because it is an old computer with low configuration; 3. It takes time to open the attachment. We received hundreds of resumes after we advertised for jobs. Even if every resume wastes a minute, we can't afford to wait. Attachments are easy to make mistakes, so all the resumes I received are garbled. There are other inconveniences that I won't describe one by one. You can paste the file directly into the email body, which is very simple! I hope you can succeed!
