Pros: Collaborative culture, competitive pay & benefits

Cons: Work-life balance is not always good.

Pros: I'm coming up to the end of my first quarter and continue to be blown away by how fast we can move, even compared to tiny startups. The engineering culture is aligned to enabling you to try things out, get things done, and get them shipped out at an amazing rate. The perks are amazing, and the management structure feels flat and low friction. Lots of smart folks and plenty of opportunities to get stuck into different areas if you feel like a change. Work/life balance is good; lots of encouragement to take a break when you need it, with a pretty high frequency of offsite events and flexible working hours. The onboarding process is very well put together: culture infusion from the moment you walk in the door, and you're mentored through a six-week bootcamp and can be pushing code out to the website in your first week.

Cons: The flip side of the low-friction management structure is that you need to take on more ownership of finding high-impact work. Don't expect work to be handed out; you need to identify the work and then get it done. I see this as a plus, but it can make it a little difficult when you start out. Having a high density of smart folks can make it feel more competitive than it really is, and that, combined with the pretty low average age of employees, can result in the occasional abrasive conversation. Being privy to the roadmap and our plans overall but not being able to tell people about it when they interpret our steps towards our grand vision in a negative light can be frustrating.

Pros: - Pay is top of market. - Coworkers are very smart. - RSUs are very competitive and performed well in my time there.

Cons: Extremely political, with lots of people playing games to try and take credit for others' work or push blame around. At review time, one person deciding they don't like you can claim that you hurt their feelings one time, and based on anecdotal evidence alone, kill your promo or lower your rating. You are constantly walking on eggshells. Code quality tends to be poor. To be fair, the product isn't exactly critical to the day-to-day operations of the world, and Facebook being down for a few hours isn't going to kill anyone. Teams focus on getting products out as quickly as possible with little concern for quality or maintainability. There is no QA department, and you will not be rewarded for taking extra time to make your project high quality.
