I moved from a software engineer position in the games industry to a similar one in finance. My current environment has a better gender balance than my old environment. However, reading CVs of potential candidates for roles on my team, my overall experience is the same as it has been throughout my career: the proportion applying for software engineering positions is low. Few women apply to join or lead software engineering teams in finance. Few women applied to join or lead software engineering teams in the games industry (the balance on the art team swung the other way, however, and QA was about 50/50). Few women applied to the embedded company I had my first job at. In college, there were over a hundred male students studying the same major in my year, and one (sic) female student. In high school, the computer lab was filled with boys. You have to go all the way back to middle school age to see anything like gender parity. This is all anecdote, and it's software engineering - I'm sure the situation in other parts of finance will be different. But I suggest at least part of what is happening happens much earlier in life than the finance institution, and effort must be applied there if we genuinely want to help.
