When you fill out and update your resume, headhunters usually contact you on their own initiative.
If you see your favorite company, you can also deliver it directly. There are headhunters and corporate HR on the recruitment network.
Nobody contacted you. Maybe it's because your resume is not well written or updated frequently. There is a button to update your resume. If you update frequently, headhunters and enterprises will know that you have recently updated your resume, that you need to change jobs in the near future, and will contact you.
