Earlier quoted context omitted.
I'm currently trying to hire multiple C++ engineers. We have a quick, simple automated test that we use as a pre-screen, and so far no women have managed to pass this test. Not that I'm actually surprised; the ratio of applicants is also biased about 50:1, and we haven't had 50 people pass the automated test yet.
Let me guess, codility/hackerrank nonsense. No wonder you can't hire.
We on the team all went through it retroactively, and all got decent scores.
And actually, we aren't having any issue hiring - it is ticking along nicely and I couldn't do more interviews while maintaining my sanity than I already am. I brought it up because I'm still surprised how much gender bias there is among the applicants.
