I was referred by an employee and received an email reply within 48 hours (October 28). My recruiter set up a phone screen within the week. It was a 45-minute technical interview for which I found a solution. Again, within 48 hours, I received an email saying that I had passed.

Facebook gave me an option of three "University Day" on-site interview dates, each about a week apart. I chose the last date, December 3rd, almost a month later. Facebook covers all travel fees, so there are no worries about the cost of flying across the country.

The internship on-sites start with:

• One 45-minute interview
• Lunch (good food!)
• A tour
• A quick presentation about why Facebook employees love working at FB
• An open Q&A with new FB employees

By chance, my recruiter was hosting the interview group, so I received a super early-bird heads-up that I had an offer before I even left FB headquarters! From what I gather by talking to other interviewees, you might have to wait 3 or 4 days to hear back from your recruiter. Good luck, everyone!

Facebook loves graph theory and tree questions. Study up on these for sure.

I feel like my questions were of average difficulty, not hard by any means. Some of the other interviewees I talked to received recycled questions that I've seen on this site and on Careercup.
