> (and it's worse when people point it out -- I was asked an interview for a programming teaching position at a university BY A PROFESSOR "how will you handle it if people don't take you seriously as a female?")

There are good ways and bad ways to broach the topic, but this is an important question to answer. Not as a hiring filter per se, but as a likely problem that needs a solution.

I went to college with (And teaching-assisted / tutored) classmates older than me, and I had to deal with the issue of "how will you handle it if people don't take you seriously as a young person?" (I didn't deal with it very well, until I got old enough that a couple of years of age difference wasn't significant anymore. Gender doesn't fade away like youth does, so gender-related issues needs active problem-solving)
