Pros: Great tooling for developers, leading to better workflows. Ability to make an impact where you see fit. You decide your day-to-day, as long as it aligns with the company's goals. Supportive management.

Cons: The internal culture is great, but I disagree with what they do externally.

Pros: I really feel as though I've found my people. I've had this dissonance in past roles. Ever since academia years ago, I've been out of the "research" phase and into the "engineer at a X company" stage, where "X" is occasionally a software product but more often a service or commercial product. The culture was not one of making the right things, but making the profitable thing now. Driven by salespeople, there was a lot of grandstanding and peacocking, both in the culture and in the message. Facebook has my people, my culture. We do things in the way that scales and makes engineering sense. Sure, perfect is the enemy of good enough, but if a temporary shortcut remediates a problem or a need, it's quickly iterated to improve, all the while immersed in a tech culture: Pusheen, Archer, Dr. Who, Star Wars, memes, the micro-actions that continually reinforce a culture-fit or a culture-miss. I'm in the culture fit. Sure, I get a very competitive salary, plus my tech chops improve (when C++ gurus review your work, your C++ quality improves), and the food, and the perks, but above all, this is the place I feel I most fit. I'm in my mid-40s. I "get schooled" by my mid-20s. ...and it's awesome.

Cons: Pace is a killer. The work is complex, as are the discussions about it. I have little fuel in my head to code after work. There's a big personal desire to keep up with the more efficient engineers. I don't want to "pass-a-fault," but I want to "move-fast" and get all the things done. It's exhausting!

Pros: Working with incredible people. Working on something people all over the world use. Being able to work without bureaucracy. You also get to work on problems that may not fit in your direct scope, which means you learn as you go and might find your next position without even trying. Great perks: * Food * Shuttles * Haircuts

Cons: Getting fat from the free food. Have to work hard, not for someone who wants to coast.
