I don't think an MCSE tells you much about hiring someone to do work that is mostly about learning and creating - software engineering, network architects, infrastructure admins, etc. But i can imagine it being useful if you're hiring someone for a position that is more about routine problems and customer service - IT support, cabling, audio-visual, etc.
I should add that i don't mean this as a slight on our comrades in first-line support. They are a vital and valued part of the IT community!
