I interviewed at age 42 with an early-stage startup composed of a handful of twentysomethings. They asked me on three separate calls if I was concerned about how young they all were—which in retrospect seems like a veiled form of ageism. They ultimately told me that their company was not yet ready for someone with my "level of experience". I wonder if I should have sued them.
