It has been my experience that Startups in the valley expect you to work for at least 10 hours per day, everyday. For example last year I interviewed with a former YC company and they were saying that it's not uncommon for 90% of the team to still be in the office after 9:30pm. Occasionally putting in long hours is a requirement of every job. I understand that, and in fact prefer to work late some times. But working past 9pm every night, never seeing your family, never doing anything with anyone outside of work? That's just absurd. Unfortunately that's the culture of the Valley.
