Pros: Great benefits. Work-life balance is good, depending on the team.

Cons: Lack of opportunity for impact early in career; product/company not regarded highly by public.

Pros: Great compensation and perks. Chance to meet awesome professionals and learn from them. Great to list on CV. Chance to see and work on services used by billions of people. Great chance of career growth if you are a junior or mid-senior engineer.

Cons: The performance review process (called PSC) is frustrating. It feels like it's very hard to improve your rating or get a promotion at a senior level. It's more about being liked by the manager and getting a great scope to work on. The code quality is surprisingly abysmal. I would again blame the PSC structure. Most of the codebase is unowned or even abandoned and not documented. To accomplish anything, there are a lot of painful processes to go through. Consequently, the coding experience is quite bad. Surprisingly, this is no longer a company where SWE is the ideal role. Nowadays, it's much better to be an Engineering Manager, as they get rewarded mostly for team impact, but they don't need to prove correlation. So, they can just cuddle a few high performers and make the bad ones' lives miserable so they'll change teams fast. The hardest part of being a manager, helping reports' careers, is really not a thing at Meta (for senior engineers).

Pros: Great benefits - one of the best health, dental, and vision insurance plans, on top of delicious free food, shuttles, and a generous salary. Good pay. Currently, internal mobility is not too difficult. You do have to be in the team that you started on for at least a year before being eligible to change teams, but it's not hard to do so after that.

Cons: * Lots of politics and fighting for scope. * Culture/WLB has recently gone downhill due to everyone being worried about stack ranking. Folks are less willing to help onboard new folks (could be intentional due to stack ranking or unintentional - too busy, can't prioritize onboarding). People frequently work nights and weekends as well.
