If you put your resume in Zhaopin for a long time, but the company doesn't reply, is it brushed (campus recruitment)?

It's basically been brushed off. If many companies recruit people, there will generally be a position dedicated to online recruitment. If your resume doesn't respond, there are two situations, either the company has recruited enough people, but you may become a reserve resource, or your qualifications don't meet and you are directly brushed off, but both of them basically declare you hopeless for the time being.
