There was a post over at Reddit asking how people can manage working 50+ hour weeks:
How do people work jobs with 50+ hours every week and not end up sick?
I applied for Space X and the recruiter was dead serious about it being a lot of hours and he pushed 65 every weeks.
How the hell is that sustainable for even a year. I decided to not go forward but I’m dead tired after 50 this dudes doing 15 on top of that.
