In looking through the comments on Derek's post about his site shutting, there was a link to here, talking about recruiters. WOW> I didn't really think it was that bad. My jobs have all come via recruiters. In my current role, I have moved to exclusivly using them to fill spots. They bring me higher quality people than I am getting via monster/biospace/craigs list. HR makes me post and advertise to places, but I try and limit it to what I have to in order to keep them happy. It just drains my budget to do that.
I get an unsoliciated call/email a day for new positions. I am pretty good about writing back to people saying "thanks, but no thanks for right now". You can sort of smell the useless ones that don't know what they are talking about. Those, I am still polite to. I got my current job becuase a recruiter sent me in for the "wrong" job, but the hiring person recognized that I would be useful for what I am currently doing.
So - I pretty much disagree with the poster at the medicine vault pretty completly. To get a senior position I think they are the ONLY way to get the job. For entry level positions, I am a lot less sure. Would guess that you get a lower quality recruiter at that level, so the posting might be accurate or reflective of that - but that is buried in a little sentance at the end of the post.
