I apologise if I missed something here, but the GP said: "I haven't really seen/noticed women not getting promoted/paid less just because they are women"

You have provided statistics that show women get paid less than men in technology. But this does not show that women are not getting promoted, or are getting paid less, just because they are women.

Is it not also another plausible hypothesis that they are getting paid less, because, (for example) they make work/life balance choices that focus less on career advancement?

This of course, might indicate that there are other issues to be addressed, with how society structures work/life balance, gender roles etc and this is well trodden ground; but statistics that show women get a lower average (or median) pay do not necessarily show they are getting paid less, "just because they are women".

If "work/life balance choices" is code for "making babies", then yes, but you made have noticed that it's mainly women who have babies. :)

Pay rates until primigravidity are lower for women than men in most industries and (less) low for men than women in a few. After that the "male bonus" increases more than the fertility rates would suggest they ought to. There are lots of conclusions that can be drawn from that, but I think the most obvious one is that employers haggle down women returning to work from childcare, and that from that age women pay a penalty "because they might go and make babies". There's some evidence (comparison with other countries with different patterns of childcare) that this is the case.

I definitely feel like many employers look for young men. There seems to be a particular mindset associated with being young and male that employers look for: the earnest young coder who'd rather spend his evening in front of a screen than go out (I can relate to that part!) and is happy to stay late in the office doing unpaid overtime in exchange for feeling like part of a gang.

I believe women and older candidates get less of a chance at interview because they are seen as less likely to be interested in putting up with that and may disrupt the clubhouse feel of all lads together.

Obviously it's not absolute proof but I know plenty of fellow programmers who've been expected to work 60+ hour weeks on 37.5-hour contracts, where anyone who's reluctant gets shunned by coworkers for not getting into the company spirit and is let go quickly. And those places have been almost all male and mostly under 35.

This is of course not just to the detriment of women, older men and anyone with a family, but also the young men who get manipulated into working hours they're not being paid for.
