Few days ago, Facebook transferred Greg Badros, a Google Senior Director of Engineering. As a man who graduated from Math and Computer Science simultaneously, Badros had been working in Google since 2003. He will be, like in Google, Director of Engineering in Facebook. What makes his transfer interesting is Badros was the team leader in several Google projects like "Google Calendar, Google Reader, Gmail team" and especially

Google AdSense Team. This shows how much Facebook gives importance to online ad services in the times of people discussing whether social websites’ ad capabilities is more powerful than traditional search engine ad services. Moreover, this can be another big challenge for Google recently, after Microsoft's announcement of Bing Search Engine.
Here’s Facebook’s official statement :
“Greg Badros has joined Facebook as a director of engineering, reporting to Mike Schroepfer. Greg is one of the most accomplished engineering talents at Google, and it’s wonderful that he has decided to bring these talents to Facebook and take on numerous responsibilities across the engineering organization.”
