Pros
The best thing about working for Amazon is the company you'll keep. It's energizing every day to be surrounded by colleagues who are incredibly intelligent, curious, and driven. The leadership principles truly guide daily decision-making and inspire everyone to consider the customers (whether internal or external) in everything we do. My colleagues have always been respectful and kind, and it's truly a fun place to work if you love challenge, creative thinking, and maybe a bit of organized chaos. Amazon is agile and pivots quickly - we like to fail fast; you can't get too attached to an idea or project, since it could be ditched tomorrow in favor or something even better. It's always Day 1! There is so much to learn and explore, so many groups and projects to get involved with, that there is never a dull moment. It's also deeply meaningful to work for a company that shares my core values around equality and climate change.
Cons
Amazon isn't for everyone - if you need predictability, conventional structure, and lots of hand-holding in a 9-5 environment, this probably isn't the best fit for you. You can forge a great career here, but the onus is on you to drive it yourself. You can easily find yourself headed for burnout if you're not careful to tune out the noise, prioritize well, and closely manage your involvement in extraneous activities.
