> Now that I'm in the system, the other stark reality is that little of this system design matters. Most of the challenge is understanding the internal technologies and figuring out who to talk to to get stuff done (like pretty much every big company).
A few years ago, I did my round of "big tech" interviews as a manager and was somewhat naive in that I did zero prep work, but I did have almost 2 decades of actually building systems. I found system design to be the "easy" and fun part of the process (including at Google). However, if I didn't have experience with scaling and redundancy in web applications, it wouldn't have been nearly as fun.
That said, once I was in the door (different big tech co), there was absolutely zero need for any of that knowledge. Now that I'm back at a startup, it's all relevant again!
