Google is vehement about not forbidding remote work, at least during the hiring / interview process.
(That's part of why I ended up at Mozilla. No two of my immediate teammates even live in the same state at the moment.)
I'm having trouble parsing your statement: mistaken double-negative?
(I'll delete this comment if your wording is clarified via in-place edit...)
Gah, I edited from "not allowing" to "forbidding," but missed the "not." Oops! Thanks for the heads up. In summary: Google does not allow remote work.
It's team-dependent. Some teams don't allow it, others only 1-3 days a week, and others allow complete remote. In general though, you are unlikely to be allowed to unless you've been there a while.
