Could also look at careers like "developer evangelist" and "solutions engineer", both of which are technical but much more people-oriented than being a regular software engineer.
The evangelists also have to deal with not just the environment at Microsoft, but also the partners we were helping architect solutions for. On more than one occasion I know women had problems delivering solutions to a partner because that partner had blatantly sexist stakeholders who would constantly try to question or circumvent them in ways that didn't happen for men. One of the college hires I was mentoring was the point person on a project, yet every single question was sent my way and I had to keep redirecting them to the woman who was perfectly capable of answering the question and was actually in charge of the account.
So yes, there were a lot more face to face interactions, but the women still didn't stick around for these roles. Some had much better experiences actually writing code on the product teams. Some moved into project management or research.
Data to support this hypothesis here: https://slatestarcodex.com/2017/08/07/contra-grant-on-exagge...
ObGyns are 85% female, Pediatrics 75%, while radiology is 72% male and anesthesiology 63%.
There's this hypothesis that men statistically tend to pick jobs involving working with and treating patients as things, and women tend to pick jobs involving people and socializing. Medicine as a field is full of high-status jobs of both kind, so - under this hypothesis - gender parity of the overarching field is entirely unsurprising. And, as predicted, individual specializations tend to show strong gender skew.
Law is also a very large field, so I suspect the profession probably shows a similar dynamic.
Viewed through this lens, our industry is less like "medicine", and more like "radiology". And I suspect - but didn't check - that if you expand the definition of "software" to include supporting fields like design, UX and testing, the overall gender ratio will be much closer to 1:1.
