  Research shows that men apply to jobs if they meet ~60% of criteria, but women and those in traditionally underrepresented groups tend to apply only if they check all boxes. If you think you have what it takes but don't meet every single point above, please still get in touch. We'd love to chat and see if you could be a great fit.
