Just yesterday I received an email from a recruiter saying that she had come across my resume and I looked like a great fit for a position she's hiring for. She asked me if I'd give her a call to chat about my experience and so she could tell me about the position. She obviously didn't remember that five weeks ago we talked for 30 minutes on the phone when I explained what I've done and exactly what I'm looking for. As I recall from that conversation, I kept telling her what type of company I was looking for, and she seemed to ignore me and ask me repeatedly if I knew .NET, which it clearly states on my resume that she liked so much that I do. Are recruiters incentivized to ignore everything you say?
