Pros: Excellent working environment. People are also kind. The hardware equipment is very high class, allowing people to fully focus on their own work.

Cons: So stressful. The manager keeps pushing people, and there's even no time to take a break. I ended up getting laid off because of performance, which is really not a good experience working in the company overall, speaking.

Pros: Facebook is a good company to work for. They pay well and have great perks. At the beginning, life is good. Facebook rewards ambition.

Cons: The appeal quickly wears off. Your experience at Facebook highly depends on the team you join. Facebook does not have the best people managers. If you join a team with a good manager who knows the system, you will be more likely to have a productive, prosperous time at Facebook. If you join a team with a bad manager, your work-life balance will be horrible. You will feel extreme pressure with the performance cycle review every six months. Worse yet, you may even blame yourself for what's happening, not realizing the role your manager plays until it is too late. Facebook is a good company for new college graduates. Even with a bad experience, you can learn so much about practical, applied technology here. For those with several years of experience, or with family commitments, be careful. Come into Facebook with a clear sense of what you need from Facebook that you cannot get anywhere else. Be prepared to leave when that is delayed, or not a possibility, or comes at a cost to your family or external commitments. For most people, Facebook is not a company that you join and happily work at for the rest of your life. Facebook is a temporary stop that will squeeze as much productivity out of you as it can. When that stops, it forces you out or makes you want to leave.

Pros: Open culture, challenging status quo is sort of expected of you; you have a large degree of freedom. You can deliver things at scale fast (that's actually expected of you). Smart, often brilliant and well-meaning people to work with 95% of the time. Focus on people (both employees and users). Good compensation (if you compare things within the UK). Handled COVID really well.

Cons: Onboarding is a hit-or-miss; you need to be very conscious about what team or manager you choose. Managers are a "hit-or-miss" too (this is particularly true for EMEA). There is a lot of change, often a lack of continuity, and a lot of friction (in org, code, ownership...) due to this. There is often short-term thinking; people are smart, but incentives are often set up in a way that encourages short-term thinking. You cannot get away with simply being a great engineer; you need to be a sort of social butterfly and build personal connections as well to meet expectations. Unless you are very conscious about your own growth and career, you can have a hard time growing. Hours can be long in order to meet expectations (WLB can be especially challenging if you need to work with the US west coast). There is peer pressure to achieve more and more and more... This can lead to a vicious cycle and often burnout. Differences in personal circumstances (and willingness/opportunity to put in extra hours) are not really taken into account when impact is measured.
