Why is the recruitment information always hanging, the resume looks interesting, and the contact information is obtained without calling?

Your resume is widely invested, and so is the employer. Check your contact information to let you know, and then I will call you after a long time, saying that I was interested in contacting you at that time, but I couldn't contact you in time for some reasons. This will show that the recruiting unit has never given up on you and reduce your dislike of it! So as to reserve relevant talents, too many people will not interview in the company!

If I am interested in being viewed, can I call myself? Didn't the recruiting unit call? I don't quite understand whether this intention is active or passive. Thanks to Q user: Ms. Zhang.
