Roughly how many points does a recruiter get?

[Quarrelsome]

30 - 40% in my experience in the UK. It's pretty sickening.

That's the default. If you're crafty there are ways to force it down over the course of the arrangement.

I've heard 10% at my current company.

20% is standard. Companies with high standards will often pay more. (One company offered 50% for a very high-level position).
