How can executive recruiters be better at their job?

It's common knowledge that most executive recruiters are terrible at recruiting. As many in the GC community use the services of executive recruiters, what advice can we give them to be better at their job? A few pointers I can think of are: (1) let the recruit get a word in every now and then rather than just talking the whole time, (2) listen to what the recruit has to say rather than constantly trying to tell them what you think they want to hear and (3) try being a little more honest in order to develop your reputation for the long-haul. Does anyone have additional tips?
