Recently a headhunter told me a couple of large companies have switched departments entirely to Go, in my area, but only hire people who "are really into Go", meaning lots of experience and knowledge. The companies, iirc, were Monsanto (now Bayer) and Mastercard.

Go still seems pretty niche here. Even the companies you mention are still mostly using Java, but I do know of teams using Go on certain projects at those places.
