So many modern experiences that are built into our improved quality of lives; apps on phones that can know my tastes and preferences, hailing a cab virtually, a bonkers level of selection of goods to all consumers, low friction same-day delivery, far greater access to online services including education and financing, just wouldn't exist (or at least not as quickly) if weren't able to cut down so many old-school structures and replace them with much more efficient and available alternatives. Getting to create a transformation in digital infrastructure and logistics at that level is just nuts. And there's still plenty to do. The money is great too; a far better result for me financially than the startups I worked at.
But all that said; Amazon isn't for everyone. It's probably not for most people. I don't mean that in the "Amazon only hires the best" sense. That's true, but so do the other big tech companies. It's more that you have to be a particular combination of driven and outcome focused with a relentless tolerance or even insatiable need for urgency, hard work, and trade-offs.
If that resonated, and you have an opportunity to join Amazon towards the middle or advanced stages of your career; definitely try to do it. I interviewed several times at Amazon to get in. But if you are at the earlier stages of your career; choose your team and manager very carefully and care a bit less about the company you join. That will make a bigger difference.
