I've had three Facebook interviews for three different software-related roles in the last few years, in different locations.

Each and every time, there's an experience so far left field that makes me think, "Hmm, that was awful." I shrug it off, but it's common enough now that I think it's just representative of the culture you hear whispers about at Facebook Seattle.

• First Interview: Interviewers don't smile, at all. As if Zuck was watching them and would fire them if they did. I figured they were just stressed from a release, so I shrugged it off.
• Second Interview: A few smilers. But one of my coding rounds had an interviewer who came in in his classic hoodie, didn't speak English, wrote the prompt on the board, and scrolled on his phone for the rest of the interview, generally ignoring me.
• Third Interview: Interviewers were actually nicer this time. But unfortunately, my lunch buddy spent the entire time complaining about the culture: the work-life balance, the up-and-out culture, and the general toxicity. I have never had that happen at any other onsite and probably never will.

I'll probably keep interviewing for practice, but I think I've written Facebook off as an employer and suggest you think about that yourself.

Some Dynamic Programming questions. Don't believe the rumors that they banned them, because I definitely got a few.
