now, we don't know if this joint was one of those "haha, yeah, we'll get back to ya" things in management's eyes from the start, but it sure looked like its leadership either was not informed or intended to make it actually matter. praise ought to be given there, as this industry seems largely morally bankrupt. however - and i'm not intending to be super negative here - she may have known that her and G weren't gonna work out, and this was just the most spectacular way to set sail.
I've met and worked with a small, couple of handfuls of google people, men and women, all amazingly skilled. Meredith Whittaker was one of them and I think her termination was unnecessary. I do think less of Google as a consequence.
