I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Jan 2015
Interview
Contacted by recruiter and had what seemed like a screening interview. That was followed by two technical interviews. All three interviews were over the phone. My technical interviews took place over collabedit.com, which is a google-doc like text editor. My screening interview was a half hour, while my technical interviews were suppose to each be 45 minutes. My second technical interview was exactly that, while my first went longer.
Interview questions [1]
Question 1
Given two strings, determine whether they are one "edit" apart, where an edit is an insertion, deletion, or replacement of a character.
