I haven't seen a single criticism of the paper that even recognizes the author is referencing large-scale incontrovertible research involving the Big-5 personality model (the giveaway is the use of terms "agreeability", "conscienciousness", "neuroticism"). Instead we get what you offer: off-hand casual assertions that there must exist research which runs against large-n and replicable science-driven studies using the only mainstream and empirically-supported model of personality that seems to work.
Basically, this makes criticisms like yours on-par with climate change denial in the sense that they either fail to grasp the point being made or offer personal observations on irrelevant points as rebuttal. It is bad news for Google either way, since the author is correct to point out among many other things that high levels of "agreeability" are demonstrably bad for anyone to have in corporate environments, and if this affects men in the same way it affects women then why are the solutions gender-excluding? Anyway, perhaps you should research the Big-5 model if you aren't familiar with it: very interesting new research coming out on it continually.
