Should the fresh graduates of the 20th14th class call the company to ask about the jobs they are interested in before submitting their resumes?

It is more appropriate to call HR after submitting your resume. You can ask the other HR if you have received your resume first. Don't write salary requirements on your resume, and don't ask this on the phone. You can express your desire to join our company on the phone. There is no salary requirement, just hope to be hired by the company. Don't say that your purpose is to gain work experience, so HR people will think that you are just here to accumulate work experience, and you will quit your job after a long time. You can ask the other person's requirements for the post and say that you will work hard according to this requirement. That's the point. Conducive to being hired by this unit.
