I applied through a recruiter. The process took 2 weeks. I interviewed at Meta (Chicago, IL) in Nov 2012
Interview
I was participating in Facebook Midwest Regional Hackathon, and got contacted by the recruiter shortly thereafter at my university. We scheduled the first phone interview, which was a technical interview. The questions included printing binary search tree in reverse, finding k-th largest element in O(N) without modifying the node, and then same k-th largest element in log(N) time keeping the size of the subtree in each node.

Question 1
"Reverse" of the problem if finding k-th smallest element in a tree: I had to find k-th largest.
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.
