I know that this isn't really the point of the thread but companies don't give a flying f* about 'equal opportunity' for women. What they really want is a larger pool of cheap labour who are up to date on every new technology product invented 5 seconds ago and work 24/7 like robots without complaining. But D&I makes great headlines!
Apart from the usual sexism like talking over women, treating us like idiots etc there's a constant need to keep learning outside of work and the tendency to understaff. Many women leave after having children because they don't want to work unpaid, so much anymore, while I see my male colleagues with children still grinding. Especially as we are managed by people who have no idea what we do or how it works but they wanted it like, yesterday. If you need to know something for your job this should be baked into the role but that rarely happens.
Of course, as much as the above is an issue it's worse in other professions. Tech has higher earning potential. However, there are massive boom bust cycles and I know for certain quite a lot of companies, while going to GHC and 'hiring' as early careers are in the budget, are making other staff redundant.
Also... ageism..
IMO the constant 100% focus and commitment required to the extent of time for actual living is also an issue that pushes women out in academia. But tech's only getting focused on now because demand 'supposedly' has rocketed. In reality companies don't want to train people, those in charge don't understand the level of skill required because 'the internet has free stuff and this 16 year old managed to do it' so it becomes an endless treadmill.
