Tell that to the non-senior SDEs whom either (1) don't have the clout with management yet, (2) don't know any better, or (3) have drunk the the lines of "work hard, have fun, make history" a little too deeply.

Enjoy your seniority; you're harder to replace. But don't apply that experience liberally to the rest of Amazon SDEs.

do you choose that time by choice? or if you didn't have a meeting at 8:30 or until 5:30 would you have to really work that hour? That's more what I mean. Not that the hours can't be reasonable. On my team sometimes I work till 4, others I work till 5 kind of thing.
