From what I remember the recruiters would surf linked in and post on job sites. For context, that was a pretty average product company in the Fintech space.
I can imagine people with strong sense of ethics not really wanting to work in fintech
Just my opinion, but if you work in software you likely have significantly diluted morals and ethics. We work in a highly extractionist industry. For that reason, I doubt that was the issue. After all, Google and Facebook still get lots of job seeker traffic.
Maybe your opinion, but I'm not sure how you could come to that conclusion. Software is a critical part of people's daily lives and the successful functioning of modern society. Some, but certainly not all, software developers actually work on systems designed to improve some aspect of the human experience and not on systems designed to continuously extract money or attention from their users.
Those things aren't mutually exclusive imo. You can be helpful and extractive. A good example is implementing automation that replaces a job and not advocating for retraining for the people impacted or implementing procedures that encourage human oversight. Another is creating targeted tracking systems. Advertisements are generally viewed as a positive for the business world and a net negative for humanity. Working on the more inane parts of these systems doesn't make you less culpable.
And I'm sure all of those Google and Facebook workers are also using heavily inflated resumes
