And then there's the second gender bias trap: As you point out, being "a natural" (or having confidence, even) is perceived as a male trait. So, if you try to increase your chance of being hired by saying you're a natural (or similar), you'll be working against gender bias. That will cause you to be perceived as somehow not feminine (don't get me started about that) and that will put people off. All of this is unconscious, of course, so people won't articulate all that. They'll just feel uncomfortable and then say things like "She seemed arrogant" or "She didn't seem authentic" or "I just didn't like her" or "We didn't click" or "She might not be a good fit" etc.
