Sounds pretty terrible to me. When are you supposed to enjoy life if you are in constant competition?
Prestige and the perception of it is a huge part of self-worth.
I’m starting to get the impression, though, that if I want to be happiest as a Big Tech Co. engineer, I really just need to work at Google.
Google is far better in this regard.
Also, caused by years of neglect and patchworks, whatever teams deal with basic infrastructure (DNS, load balancing, corporate infrastructure...). Though none of those are in Seattle anymore, IIRC.
What school did you go to? Went somewhere similar.
My school recommended 3.5 hours of work outside of class for every 1.0 hour of lecture (roughly equivalent to credit hours with rare exception). For the minimum full-time load of 12.0 this equated to 54 hours a week (12 hours of class, 42 hours of outside). 18 credits was 81 hours a week all in, and this was expected. 100-level classes were typically less but my junior year particularly it was pretty much spot on.
