I interview candidates for developer positions and the bias against women in the (Australian) developer job market seems plain to me.
I work at a smallish company owned by a bigger group of companies, it is a nice place to work and family friendly, but not at the top of many people's list of exciting places to work.
I don't know all the filters between me and the people submitting their resumes, but there are lots of stages and filters and the process is slow.
As an unexciting company we're not getting the first draft picks from the market. By the time we get internal approval to offer a job to someone, more often than not men have another better offer, women generally don't.
I believe we are able to hire women with skills and experience that would not be as available to us if they were men.
Part of the dynamic would be that our company is very family friendly, and on average women are prioritising that higher than men, and thus on average ranking us higher than men, and therefore some of the bias is structural, rather than being entirely driven by personal misogyny of the recruiters and interviewers.
But that would only help explain the higher availability of excellent female candidates who are prioritising raising a family, it doesn't explain my belief that we have disproportionally been able to hire women with standout level of skills and experience no intention of ever having children*, candidates that I believe would be much less likely to be available to us if they were men.
(* no - I didn't ask that in the interview, I learned that afterwards, when we were work colleagues! )
