- Facebook purposefully hires very smart and ambitious individuals. Even when there's no pressure from the manager to work long hours, you often see people working long hours, which in return puts more pressure on you.
- There are no incentives to stay in the company for longer than 4 years. Once you vest all your RSUs, refreshers you get for good performance look very unattractive. It's more and more common for people to leave FB after 4 years, and come back a year later to re-negotiate their RSUs.
- You are being "punished" with certain benefits if both spouses work for Facebook. A good example is baby cash which you get per family, not per employee.
- Commute in the Bay area is terrible.
- It's getting very very crowded in MPK. Facilities are definitely not keeping up with recruiting.
