So is this an acquisition or a recruitment drive?
From some local rumor (maybe from HTC's Taiwan employee, but not confirmed yet), Google won't acquire all team member, they want RD mostly, not the management people.
And google will have a internal interview for those RD to decide who can stay, then sign a two year work contract with them. so that's some different compare to other google employee.

Rick Osterloh will come to Taiwan for detailing the next step to them.
Do you know what's happening to them?
The mail only says he will go to HTC's Taoyuan and Taipei office today. and almost all announcements specified the "Pixel team".
Maybe the team is located at the two office only.
