Throwaway account. I recently had an interview with a start up from the latest YC batch. First words out of the founder's mouth, after hello: "So, how old are you?"

For a moment, I was speechless.

Not sure if it was just social awkwardness and shyness that made our young founder jump to that question. But in what universe is that ever an appropriate question in a job interview?

(I'm in my early thirties.)
