While I've always understood overtime for startups, or to solve an unexpected problem, I simply do not understand why people put up with systemic overtime for large companies making large amount of money. They are simply abusing your time, you should refuse. They are saving money by not hiring enough people. It's management saving money, or being incompetent, but then it's management's problem, not yours. Of course, during difficult times one may have no other choice, but I'd just run asap.
