Pros: - Smart people all around. - Pretty much some of the highest tech you can see in the field. - Perks. - Salary.

Cons: Lots of stress if you're on a high-profile project. Performance reviews are nightmares. Company direction is getting awkward. Too much external politics in the office.

Pros: Most skillful engineers in the country.

Cons: In my position, I had a lot of influence in hiring and terminating employees. I have been exposed to dubious decisions in that area by upper management; actions taken without good heart and with conflicts of interest. This behavior could only thrive in our cult-like company, where truly speaking your mind could hurt your career. Quite ironically, the values of giving constant feedback are encouraged at Facebook, but in reality, employees are afraid of giving negative feedback, as they know the potential devastating consequences of doing so. Negative feedback will be given about technical decisions and ideas, but not about managerial decisions or the human resource department, from fear of upsetting the wrong people.

Pros: Facebook prioritizes building positive social impact. They do this over growing revenue, and this creates a hugely incredible mission-driven company. You are empowered to align personal and team goals to invent the products and outcomes that build social good. Every person that you work with at Facebook has this mindset, creating an incredibly supportive and collaborative environment where everyone is an ally.

Cons: Facebook isn't for everyone. The hardest thing that many people struggle with is the amount of ownership and accountability you are given. Because Facebook is so bottoms-up, it requires people to be able to be highly collaborative to gather information to make the right decision. No one is going to tell you what to work on; you have to decide yourself what will be most impactful. That's a hard environment to be successful in for many.
