I say this is an ignorant default to assume. You can't prove it, you can only believe it, and the assumption itself is a bit ass backwards.
And despite the fact that 11k women were hired this year, women still only make up 30% of Apple's entire workforce, per their diversity website.
I wouldn't say that at all. You can't prove it's not true either, so it works both ways. How many women make up Apple's work force isn't really the issue I was addressing anyway. If the 11k women they hired were the best qualified candidates, than great. In my mind, the fact that they made a conscious decision to do something means that they were either NOT hiring the best qualified candidates before or they are NOT hiring the best qualified candidates now - otherwise this would not ever have come up.
If you want to "fix" the issue, it is far too late to do anything at the hiring stage. Give the under represented race/gender/whatever better education and training so that they are equally qualified for the job and the issue is gone.
