It seems that all job posting I come around is looking for a one tough guy who have all certifications in their resume. I don't believe one can find an employee who knows everything from Windows networking, ISA, Windows 2008, Vmware, hyper-v etc. Maybe basic knowledge of all you can wish to have...

Most HR ask about previous job experience.So how do you guys apply to a position whom you don't have experience but you have the knowledge?
