Meta Software Developer interview questions

I have two phone coding interview over Skype. Than they invite me to offline interview: four interviews one after another in a single day. Questions was pretty hard to answer, because you should hold in your mind two major things: think very fast and to be very accurate in what you are writing in the code. That was hard for me, but I'm very happy to have such experience. Facebook was seemed to me like superior place in case if you want to spend you whole life to coding and if really like it.

Contacted Facebook University recruiter with my CV and sent in a form specifying where I wanted to work/ what I wanted to do at Facebook. I was scheduled an interview for late in the evening due to the time difference with California. Initially asked a number of questions on my CV and the projects I had worked on. Then moved onto technical coding question using online coding tool. This was a hard recursive question which I was unable to complete.
