Microsoft doesn't need to advertise for jobs beyond their own website. Also, the grammar used tells us this person isn't a native English speaker nor a professional.
Suspicious skills:
1 2 3 4
iPhone/mobile apps
Cross-Platform development.
Mac and iOS development/automation experience
Objective-C
I should have reported it when I saw the iPhone, Mac, iOS remarks, but I figured everyone would have been smart enough to realize it was fake and not comment on it. MS only develops on MS products.
