I've had a full-time job as a Software Engineer (later Data Engineer / Data Science), since I was 23 years old. I've done all sorts of programming, worked in academia, done my own startup (Scalien), worked at medium-sized successful SaaS (Prezi). At Prezi, I was promoted to a Director. I thought I'm the shit.
Then, at age 36, I got a job at Facebook [as in IC]. The first couple of months were the most humbling time in my working life. Before, I always felt I'm in the upper percentiles of whatever group I was part of it. At Facebook, I never felt like that --- I felt like I'm the median. Any problem I've seen in my previous jobs (how to manage large code bases, how to write good code, what does a good ETL system look like, how to be data-driven), I realized that I was at "version 3.0" of that space, but Facebook was on "version 15.0". Whatever I knew to be the best approach, it was evident that the 1000s of smart people who work(ed) there, were well past that stage, they passed that stage 5+ years ago.
Ever since then I always recommend people to interview for Big Tech companies if they get a chance, and do a stint. There's so much to learn from the collective wisdom that 1000s of engineers (and PMs and DSs and..) have accumulated.
