Pros: 1. Things you do impact 1 out of every 4 people in the world. If you are on Glassdoor, FB impacts everyone you know, quite literally. 2. The people at Facebook are simply awesome. Not just talented, but they are interested in mentoring and supporting you as well. The primary reason I don't see leaving the company anytime soon is the people. 3. The amenities and benefits make it feel like you are on a perpetual vacation. 4. Internal transfers are easy. You can use them well for growth and move around the company quite quickly.

Cons: 1. Workload is going to be heavy and stressful. 2. Offices are not dog-friendly. 3. PHP/Hack is everywhere and it is quite literally the worst language to work with. 4. Information overload.

Pros: Great company to work with and awesome engineering culture.

Cons: Too much focus on AR/VR (Metaverse!!) and not enough on provably big shifts such as ML.

Pros: Great benefits and great compensation.

Cons: Too much politics. Horrible middle management who only care about the number of people on their team. Your manager can present your work however they feel like to make you fall in line. HR is just there for show.
