Ever hear the phrase "Those that can't act become writers and those that can't write become movie critics?" Well many recruiters are the movie critics of the IT world.

I once tried to use a couple recruiters and they tried to convince me I was an excellent candidate for a help desk telephone support job and nothing more. I found myself a Network Engineers position soon after that.... Keep in mind they are not there to help you. They are going to help the companies that hired them to find them people. Some of the more dishonest types will even misrepresent your abilities as they are after the commission.

As to the list of required skills. Don't worry about it. As one manager told me, he lists many things and casts the net to see what he will get. You may lack a certain area but if the manager is good and can see you can grow into it quickly; he will take you on.
