But when it happens over and over and over, you can't help but feel frustrated. You realize that people natural instinct is to think you are the subordinate. One second your are on stage at Techcrunch (I was in 2017), where you have clearly introduced yourself. You get off-stage, they greet your colleague and ask him the questions as if he was on stage.
I was often in the interview room waiting for my interviewer, only to have him show up, and tell me I must be in the wrong room. A simple "Hey are you XYZ?" could have avoided this frustration.
I've written an article about my experience working as a black developer, I'll post it here in the near future. You wouldn't believe how lonely it is. In my team of 150 people, we were two black people.
