One thing I've always said about women in tech is it's not that it's overt sexism, it's subtle, it's like your credentials get tested much more in interactions. For example:
Man: I'm in IT
Others: That's cool.
Woman: I'm in IT
Others: Oh, how would you solve problem X using technology Y.
I just ignore it now, they'll work it out that I might actually know some tech stuff when they work with me for a bit, but I'm sure as hell not going to prove myself to 'Jim the new network guy' just because he wants to know what the woman in the team is doing there (diversity hire, team admin etc...).
I too don't always have the correct answer (as there is always sooo much to learn and everyday some new thing rears its ugly head!), but at least I'm at a place I can ignore the need to prove myself to everyone I get introduced to now, by simply no longer indulging it.
