Of course, and I have been pretty junior at an early stage startup where I improved and learned a lot (more than I think I would have at a larger company, at least), but I definitely wouldn’t have worked as many hours if I had more experience, and I think the arguments that center around you needing to work extremely hard (7 days a week, and/or like 70-80hrs) are predatory and have no sympathy for them. As other commenters have mentioned, if you need to exploit people in some way to be sustainable then you’re not sustainable.
