I'm a Linux guy myself but this is just a bunch of arrogant bs. Would you be able to troubleshoot AD delegation issues i a multi-tenant forest environment? Do you know differences between different patch levels of the Exchange Server? Do you know hoe to deploy, configure and integrate Lync? Are you competent in PowerShell w/o having to constantly look it up online? How Office 365 integrates with Azure cloud and specifics of how MOSI works with syndication partners? When we have a Windows problem I ask Windows guys for help.
