This is my experience as well. Often I'll be the most knowledgeable person at our booth (for Neo4j) and people always look to my male coworkers when asking questions.

And one of my personal favorites: "So I'm guessing you're in marketing?"

This behaviour needs to change, it really does. But (ugh, here we go..) this particular instance is probably learned behaviour from past conferences or situations some people have been in. I haven't been to many conferences, but there's been a few times where I've spoken to a woman at a booth just to be passed off to someone else when I've asked technical questions. I'm finding this happens less and less though. Really though, it doesn't hurt to ask the question you want to ask first, even if you do end up having to ask it again of someone else.

It's funny to me because looking at the resume of the article op, you see she is in marketing.
