I genuinely have never heard anybody have to work this much at Amazon. I can count on one hand the amount of times I’ve had to work more than 9 hours a day (it’s once, 3 year tenure).
While the above may have been a joke, its not a secret that work life harmony and culture are perhaps the worst aspects of Amazon (talking of the corporate side of course, not including warehouses)
That's insane money for just about any region in the US, outside of maybe the bay area. I'm not trying to offend you, but the fact that you're making that much as a mid-level engineer with what I'm assuming not a lot of experience and still think you're under-compensated tells me you're not connected well with reality outside of Amazon and FANG in general. In fact, you'd be lucky to be making 6 figures outside of the FANG bubble at mid-level.
