Pros: Facebook decided somewhere along the line that speed and engineer efficiency mattered more than predictability and avoiding mistakes. The result is a rather refreshing environment where engineers are expected to take risks and use our discretion to jump on what we see as most important. My co-workers are amazing – Facebook's been able to hire some of the best talent in the valley, and it shows. The perks are top-tier. It's just gratifying to work for a company with a sense of mission about creating good in the world, and that's at Facebook's heart. It's certainly helpful to love using the product yourself, but as long as you derive satisfaction from the billion people who do, you'll be happy working here.

Cons: Suspecting Facebook of nefarious motives is a popular, if misguided, Silicon Valley pastime. Usually, trying to argue people out of it is a waste of your time. :/

Pros: The office environment is good in general. Having a big name on your resume may also be good for the future. Most of the colleagues are very prepared technically.

Cons: As the company grows, they are trying to cut costs. Objectives are unrealistically set, and bonuses and promotions are considerably lower. If you work here on a visa, pay increases and promotions are slowed down even more. Mid-management gets packed with responsibilities. The individual contribution is no longer relevant. The general philosophy seems to be "it's normal for people to leave the company," and that happens regularly after every performance cycle or stock vesting time. To counterbalance this, the company seems to brainwash employees with slogans. Posters are everywhere around the office to make "the culture." Many company employees believe and talk with slogans. Life/work balance is simply set to "no life." I've seen managers complain if someone takes more than one week off in a row, or making jokes about family duties the first day someone returns from parental leave.

Pros: I love programming. I experienced 5 years in my high school and am trying to grow myself.

Cons: But sometimes, I am really getting tired because of programming. In this case, I just relax for 1-2 days, and passion follows me again.
