I think you're reading a lot into that policy which is not stated. This looks a lot like "opportunistic" hiring as it is described. In any case, this looks like more of an announcement and less of a policy document describing how to handle the edge cases on which you base your hypotheticals. In particular, did Dropbox hit its headcount target and need to use this "opportunistic" bucket? If so, how did it handle that…
> In particular, did Dropbox hit its headcount target and need to use this "opportunistic" bucket? If so, how did it handle that case? Judging management decisions in the abstract is folly. This is explicitly spelled out in the policies I sent you: the opportunistic hiring bucket is exclusive for women and URM. If you want to use the opportunistic hiring bucket, the candidate has to be either a woman or URM. What is…
What I said:
> how did it handle that case?
You haven't said a) whether this hypothetical actually happened or b) how it was handled. That leaves all this in the realm of rage-bait hypotheticals.
> Representation relative to the workforce is what's relevant.
You're defining "workforce" narrowly to exclude people who do not currently work in the "field." This is unnecessarily narrow because e.g. there are people who work in tech who do not work at pure-play tech companies in Silicon Valley (this is where the policy pulls its stats). So setting a low bar and barely clearing it.
There's also likely the possibility that they are conflating "engineering" and "tech" roles. Female CS majors are indeed ~19% in the US, but "tech" jobs often include lots of people on product teams who are not engineers: QA, UX, etc. I don't know whether Dropbox counts a UX person as "tech" or not tech. I also don't have good stats on e.g. gender balance in UX, but I would wager that it is not the same as for CS grads.
Incidentally, Dropbox non-tech is only managing 43% women. This includes roles like marketing, sales, finance, HR, etc. where the excuse of the college pipeline is not operant. (For example -- women are the majority of accountants in the US.)
