I was just at an anthropology conference where they were talking about the importance of the race/gender/… of the interviewer vs. the interviewee. A black lady said: “When I was interviewing in Africa, people told me they opened up to me because of my color and grey hairs”. The discussion was interesting, it made me think of the importance of a diverse team. In web development, usually everyone is white male, and I think it shows in the systems we build.
