I have great experience with third party recruiters. I only ever had to send them a CV (as PDF!) and they took care of the rest. I just had to go to the interview. The company hired and payed for the recruiter so for me it’s a win.

Granted, in my last two job searches I never looked for open positions myself, I answered messages from recruiters in my inbox. So it’s more that they were applying to me. Most messages can be ignored because the recruiters have no idea what they are talking about.
