I should have made it clear that it's is certainly not the majority. My very first interviews were the bad ones and I was referred to the "skipping math questions" guy by a close friend. There was some other minor shit but I felt like it was caused more by awkwardness than sexism. After my troubles I started heavily screening companies I accepted interviews at. So this was 2/8 in person interviews but that's very high because of my pickiness. I probably did 20 or so phone interviews and either chose not to take it further or wasn't invited to continue.

I also run a very large meetup group (around 4000 people) that is nearly 100% tech workers. In four years and hundreds of meetups I've only met a handful of guys that have issues with women in tech. But like I've said, the ones that really believe there's something different about women that make them not care about hard work/intellectual pursuits/math/whatever are just so hateful that they stick with you.

I ended up joining two wonderful companies that were totally accepting and I felt 100% comfortable around everyone at all times. I got a contract to hire gig at Scripted but before the hire date I got an offer from ThoughtWorks from an earlier interview. I can't even describe how wonderful they both are.

I think that it's an ugly cycle right now. It's hard for me to talk about the experiences I've had because without adding a ton of qualifiers it can sound like I am blaming more than those few specific people. Which obviously puts people on the defensive which only leads to worse situations.

I'm jet lagged and rambling, hope this gives you a little more insight.
