Pros: I moved here from a larger, stable company where I was also working as a software engineer, and I have just been wow-ed! Apart from the amazing perks, I work with a set of very dedicated, determined, and intelligent folks, which is really the best part of working here. * Co-workers are mostly rockstars! * Lots of resources to learn. Seven months into my job, and I feel I am already a much better engineer. * Lots of importance on what YOU want to work on, versus what your manager thinks you should work on. You can freely talk to your manager and find an intersection between your interests and the company/product needs. * Everything is automated (again, by rockstar teams), and processes are made as simple as possible. * Great pay, stocks, and bonuses. * Amazing perks! Lots of food choices, a great campus, regular team happy hours with great food, and the list goes on and on.

Cons: Work-life balance is almost 0 on weekdays. I spend the entire day working or thinking about work, but that is what I was looking for. Weekends are up to you; most people do not work. Lots of process changes occur in short periods of time, so you are constantly climbing the learning curve. This may be specific to the product I work on.

Pros: - Free food - Reasonably good compensation - Reasonably flexible hours - Lots of smart, capable people - Work can be exciting

Cons: Working on product teams is trying because of the micromanagement of Zuck and other upper management. Many projects get delayed because they ask for random changes. Working on backend teams doesn't have that problem, but they are typically second-class citizens and don't get as much respect as frontend teams. Facebook is very large now and the bureaucracy is starting to accumulate quickly. It used to be that engineers could just do stuff, but now almost every change requires a great deal of pointless discussion or overhead. For instance, you now have to fill out a form just to log some data. Very strong focus on some of the "hot" product teams means that the rest of the company doesn't get preference with respect to product managers, designers, etc. Most frontend work is boring, mundane PHP. The only challenge comes from poorly-designed legacy systems. Managers will often ask you to work on something you don't care about just because it's a priority for the company. This goes against the claimed philosophy of Facebook, but it's the way things are trending.

Pros: Good salary and bonus structure, with great fringe benefits.

Cons: Very high COL area, demanding project schedules.
