I agree strongly with your views on this. The qualities you seek can be hard to evaluate accurately, however, so I'd be interested in hearing any ideas you may have on specific tactics for evaluating candidates. For example, how do you find out what a candidate's peers really think of them? Do you contact the candidate's old company and ask them? How can you tell if they're being truthful? (Some folks are reluctant to tell the unadulterated truth about what they really think about someone for various reasons, e.g. fear of legal action).
I've been through the hiring process a few times and wrote a node about it a while back: On Interviewing and Interview Questions.
