Nice story.I am a retired computer programmer. As a programmer I coded the most complex application anyone in my department coded. It was probably one of the first robo call applications.When my boss hired a black programmer I mentored him, although I had not been asked to. He told our boss I was helping him. Our boss told me, "It is my job to train the people I hire, but I do not always have the time. You are making my job a lot easier." In a job review he told me that I finished my assignments faster than his other programmers with fewer errors, and that the design engineers always asked that I would code their applications..
To get that job I had to pass a mental aptitude test and a test of my computer knowledge.
