If you are applying for a big company, give up this attempt. However, if you are applying for a very small company, then take your phone number, boldly harass HR, call directly after submitting your resume or interview, ask for the general results, and show your desire to join the company. There is a simple reason. Big companies are like PLMM. If you chase too hard, you will annoy her and ignore you at all. A small company is like a neighbor's MM. What worries me most is that you are insincere and disloyal to her. The more you pester her repeatedly, the more jubilant she becomes. Of course, you should pay attention to the timing and choose a time when your work will not be too busy. As for the timing, the sooner the better. You don't want your "rival in love" and your competitors who are looking for a job to make this harassing call first. The sooner you call this number, the better.
