Everyone is not so good, and every company will respond. It is necessary to cast a wide net to find a job, increase the delivery volume, and finally increase the probability of a reply. For those who don't reply after delivery, learn to be indifferent and overlook.
Of course, if you care about a company and the company hasn't contacted you for a long time after your delivery, I think you can at least try to do the following things, which will definitely be effective. Read the recruitment brochure of the target company again. There is no reply to the submitted resume, the biggest reason may be that the resume does not match, so it is very necessary to study the recruitment brochure of the target company, read and study it repeatedly, and compare it with your resume at the same time, find out the differences between the requirements in the other resume and your resume, and then focus on it.
