If a company were to ask about my star sign, then I know that their idea of what is relevant is not grounded in reality and will avoid employment with them. Someone asking me about my strengths in high school, which was decades ago, then that tells me they are looking for young people. (And from the link at https://news.ycombinator.com/item?id=30735678 https://news.ycombinator.com/item?id=30735678 you can see they don't care about my grad school experience, which was much more formative to my career path.) In the US, age discrimination for employment for people 40 years or older is illegal. As the author of the linked-to essay correctly points out, these questions comes across like trying to discriminate on the basis of age without outright saying it. Which trespasses on a special form of government monopoly that it can enforce.
