First, you should send a resume to the company you want to apply for, and then you should call the person in charge of personnel and ask him to take some time out for an interview. Only when you have a basic understanding of your resume will you decide whether to further interview. It's no use just relying on the telephone. Of course, there is no standard for how to say it on the phone, but please be polite, introduce your name clearly and the purpose of calling yourself, such as: hello, Mr. XX, recruitment director of XX company/. I saw the recruitment information of your company on XX channel. Does your company still recruit XXX positions? My name is XX, which meets the requirements of your company. I have sent my resume to your company's XX mailbox. Please take time out of your busy schedule to look at my resume. I look forward to your good news. I hope we have a chance to cooperate. Thank you very much
