I second tptacek. This is one of the most effective places we have found candidates - we just hired our 3rd person from HN. Every candidate that has approached us through HN has been thoughtful and intelligent - although obviously not everyone is a match for what we are working on. Certainly I can offer anyone from here a actual person to talk to about your background and interests and what we are working on.
I found my current job at Monetate here, and am quite happy with the ease I was brought aboard. When I was looking last summer, it was easy to ctrl+f the hiring threads for my location. On the whole, I find the job descriptions succinct -- an immediate snapshot of what it would be like to work somewhere is important. And finally, the quick communication after I made contact gave me confidence that this place was serious about finding the right people.
