I applied through college or university. I interviewed at Meta in Feb 2014
Interview
A on-campus interview lasting about 35 mins. The interviewer is a man with red nail and red hair. Just asked some background questions at first and then start asking the technique questions. It is not a difficult one.
Interview questions [1]
Question 1
Give a set of objects and a function. Pass two objects to that function and it can tell you whether one object points to another one. Find one object that is pointed by all other objects.
