If they need understanding of the technology, I will gladly help them with that.
If they need understanding the domain knowledge, I will gladly help them with that.
If they need understanding of interpersonal, organizational, or "soft" issues, I will gladly help them with that.
If they want referrals, I will usually do what I can.
If they don't call back or follow up, I will eliminate them.
If they are ever dishonest in any way, shape, or form, I will eliminate them and tell everyone I know.
For a recruiter, brutal honesty can overcome any perceived weakness and enable others (even us hackers) to be on their side.
Steve, thanks for your brutal honesty here at hn. That's the best we could hope for and should be a model for any other recruiters lurking here. Respect.
Now I do my part to be honest, and I look for the same in any recruiter I come across. I'll echo Ed's sentiment in saying thanks and it's nice to read about recruiters who have a passion for the industry and the people in it and not just a passion for making the sale.
