>>colone+(OP)
Recently talked to 2 friends working for fb. According to them, the culture there is very toxic. For a master's degree, once get in, you need to get promoted in 22 months (I might misremember the actual number.) or you will have to leave. Debugging is never counted as a real work, so for quick promotion, nobody wants to solve bugs unless a bug becomes too obvious. And they also complained about no work-life balance. They got pushed to check-in code at 12a.m. for example.
