First of all, the headhunter finds you, which shows that the other party has fully understood you. The purpose of headhunters looking for you at this time is to have a position that is very suitable for you, or vice versa. People in the workplace need a suitable position to find a headhunter.
It is conceivable that an enterprise needs a qualified person to find a headhunter, and then the headhunter will look for a qualified person in the market according to this demand. Finding you at this time shows that you are qualified for that position. The headhunter will explain the general situation to you, and it is up to you to decide whether to agree or coordinate. Headhunters just play a connecting role.
Secondly, headhunters come to you for another purpose, that is, to fill their talent pool, which is usually done by new headhunters (I have done it). Because many headhunters are HR-transformed, most of them have their own talent pool, and only part-time headhunters will contact job seekers to fill it the day after tomorrow (just like me).
At this time, it is good for you to give your latest resume to the other party, but the more prohibited headhunters are concerned about your project experience, not your education, work experience and certificate. If you are just a newcomer to the workplace, you can start with academic qualifications and certificates, and start with projects for more than three years in the workplace.
In this way, headhunters can update your resume to their talent pool, recommend it to you when there is a suitable opportunity, and communicate with you from time to time to update your resume and update whether some positions are suitable (so as not to be considered incompetent by job seekers).
In my opinion, from the perspective of headhunters, I don't think it is the most important place in a resume, but I also suggest that job seekers and professionals fill in their resumes carefully. After all, your resume is your business card.
It's done.
