Thought I'd share a few things that happened to me very early in my career as a woman in tech:
Incident #1: This happened in my first job when I was 22, I was so naive and trusting. This person was supposed to be my mentor. Instead, he stole my work. He thought it would be okay to look at my laptop to steal my work to present it as his own.
Lesson learned: Always lock your laptop.
Incident #2: I asked one of my managers about my career path and wanting to advance myself. I was already managing a product and running UI interviews as well as engaging with customers on a brand new product line. You know what he said to me? He said, "It's hard to take you seriously because your voice is so high."
Lesson learned: Be respectful when you say this, but people need to know telling you that your voice is too high is inappropriate and should be noted and depending on how it goes, it could go to HR.
Incident #3: I was in a meeting with a bunch of colleagues, engineers, product managers, and UI, all men (of course) and we were going around the table brainstorming a solution and the VP skipped over me -_- I interrupted him so my voice could be heard. He did this to me multiple times in that meeting.
Lesson learned: Do not be afraid to be assertive. Do not feel like you shouldn't say something because it'll make you come across as a b****, because you know what? If your male counterpart said something to stick up for himself, no one would question that.
