Philadelphia Inquirer: Comcast and Amazon are going toe-to-toe this week, wooing techies in different rooms of the same Philadelphia hotel. Amazon is holding an “invite-only” recruiting event for software engineers at the Loews Hotel, seeking workers at its Seattle headquarters. Meanwhile, Comcast — which is building a billion-dollar high-rise in Philly for product innovators and developers — has scheduled its own invitation-only happy hour event for local techies at the same Loews. The Comcast event is billed as a “toast to tech in Philadelphia.”
