This was definitely a trigger for me.
A few years ago, I had some great email exchanges about a position. I was an experienced dev, and I knew what they were looking for. But to make it official, I had to go through their HR person.
This was the first time I was going to talk to someone from the company, live in a video call.
And the moment we jumped on a call, her first words were, "Do you have a green card?"
I was born here. One look at my skin color and that was her question.
