I was "inspired"by this post.
In it, Philip Su, an E9 (Distinguished Engineer) from Facebook explains how he progressed in his career, which includes an impressive stint at Microsoft that saw him promoted every year for 8 years straight.
If you have that kind of accelerant so early in your career -- you're bound to be "Successful", or at least air-quotes successful.
Distinguished engineers at a FAANG company (Facebook, Amazon, Netflix, Google..etc) are the highest technical individual contributors in companies that value (and pay) their technical folks LOTS of money. There are fewer Distinguished Engineers at FAANGs than there are NBA players, that level of elite requires immense dedication.
I'm not as "successful" as Philip. I started my career as a Business Analyst in Shell, I was promoted (sort-of) twice in my 9 years there, then bounced around a bit, and joined Amazon as a L6. I left 4 years later at the very same level, promoted a grand total of ZERO times. Now I'm a partner engineer at Google -- a peon in the giant machinery that is Google Cloud. So I've worked at FAANG companies, but at more ground-level stuff, than in the stratosphere that Philip operating in.
But, I'm happy where I am, and pretty happy with my journey so far.
