We worked hard and we worked well together. We did whatever it took to succeed. Sometimes that meant working 20 hours days on some global supply chain project. I worked with a lot of really great people and a lot of terrific engineers. Best users I've ever had.
Given what I know about Samsung in Austin, I'm pretty sure you're not paying nearly enough to justify anything close to 20 hours a day. Just because you work with "great people" on "a global supply chain project" doesn't sound like anywhere I'd ever want to work, and it seems like the attrition numbers I've seen agree with that.
Imagine looking back at 20 hour days fondly. And you were an engineering manager. Nobody does good work 10+ hours into a shift. 20 hour days are good for one thing, allowing your boss to understaff teams with no consequence.
