As somebody who has only ever worked at places small enough for individuals to all roughly understand eachother's impact, could I even get a job at a big org like that? I don't even understand the mindset
Yes of course. You have to demonstrate that you are very skilled at building with the particular bricks they use. Don't mention anything else to show your commitment to particular brick usage.
Sometimes, I daydream about being a nameless drone in a cubefarm, taking home a nice paycheck and leaving my work at work. But, yeah, the dream passes quickly because I know I'd hate it with a burning passion.
If you want to seek meaning in your work, then yes, cubicle farms will not give you fulfilment. But if you're just after a steady paycheque, and don't give a damn about the business, your work nor its purpose, then this is fine. And it gives you free time to live outside of work too.
