Chasing offers by headhunters is such a miserable experience. Your résumé will be one amongst hundreds of applicants, most of which will be filtered out by AI before a human ever reads them (using opaque logic that could disqualify you for no reason whatsoever, so if you never hear back after many applications there's a good chance something in your résumé is tripping their filter and there's no way to know what it is).

And the headhunter is probably a third-party hire not affiliated with the actual team, so the first interview will be with someone who doesn't know what questions to ask and you have to somehow make a good impression without being able to show off any of your knowledge. Basically showing good vibes or whatever. Good luck if you're a talented but socially awkward person!

Then you'll have to go through the whole interview process again once they hand you over to the people who hired them and actually know what they need. At this point you've finally reached what was once the starting line of the hiring process.

TL;DR: Fuck LinkedIn and modern hiring.
