      I applied through an employee referral. The process took 6 weeks. I interviewed at Facebook in October 2016.

      Interview

      A friend referred me and I heard back from a recruiter immediately. Over the next two weeks I did two phone screens, and a week after that I heard back that I passed and would be moving on to the team matching process.

      As this was for a PhD internship, they spent the next two weeks gathering team hosts to interview with, and finally settled on a date for 3 interviews with potential hosts. They told me as long as at least one team wanted me, I would have an internship. The day of the interview comes, I have an hour long talk with three different teams, all of which I thought went great (two of them even verbally said they would love to have me and to hear a follow-up shortly). I was ecstatic at the thought of interning for Facebook, and the recruiter told me I would hear back a decision in two business days.

      Well I didn't hear back in a two days. The recruiter messaged me a week later that it would take a bit longer to make a decision. One evening a week after that I get a copy pasted response from recruiter about how Facebook will be not be moving forward with an offer and that there were many qualified candidates this year.

      Shame on the recruiter for not keeping to original timeline. Shame on the teams for lying to me about joining their team. It's good to know they put off my decision to hire these "more qualified candidates". Given how I thought the whole process went very well, just to be pushed aside at the very end, means I will never be applying to Facebook again. There was no trust or transparency at the end.

      I applied through a recruiter. The process took 8 weeks. I interviewed at Facebook (Seattle, WA) in August 2016.

      Interview

      Overall, the process was straight-forward, but a bit slow in turnaround. I had been contacted by one of the recruiters every 2-3 months for the past year or so, and just had to give the go-ahead. Every round of scheduling seemed to take a week, and then getting feedback was another 3-4 days minimum, then another week until the next interview.

      Interview

      Phone screen (with coding). Sometimes had difficulty understanding the guy. No behavioral, pure code. Question itself was pretty challenging compared to the other questions I've gotten at other places, but not unsolvable. I didn't get a working solution, unfortunately, before I ran out of time.

      Application

      I applied through a recruiter. I interviewed at Facebook in May 2016.

      Interview

      It was pretty straight forward. The first question was to test my coding skills and the second was to test my thought process for solving problems. I spent some time on the second problem mostly because I didn't understand what the problem was (probably too much time). It seemed that the interviewer had trouble clearly explaining to me what she wanted as a result. But once we got past that, the solution was straight forward.
