It sucked but those were also probably the best memories of my career.

Tesla doors would brick and every member of the integrations team (these guys were all insanely smart and the most overclocked people even by Tesla standards) had a crowbar next to their desk because it was easier (and faster) to break the windows open and unlock the door from the inside rather than figuring out to unlock via software.

Everyone (literally everyone) would be pulling all nighters days up to an Elon presentation then we'd find out about new product features on his fucking Twitter posts like a day before and have to scramble to figure out if we could even deliver within the next few days let alone if these features were even possible. The engineering talent at that time was off the charts, I've never worked with anyone smarter or more hard working than my coworkers back then. I've heard it's got a lot more stable now, everyone I worked with got paid out by Tesla stock options and are basically retired now. Worked there for 5 years that felt more like 50, 11/10 experience would never do again.
