Meta Intern interview questions

I applied for a software engineering internship on Facebook's career website. After about a week or so I was contacted by a recruiter via email who scheduled me for a phone interview with one of their engineers maybe a week or so afterward. The interviewer over the phone was an engineer at Facebook. I was asked two programming questions. A few days later I heard back that I wasn't selected to continue the process.

Sent in my cv, e-mailed back by HR recruiter to ask a few more questions. Had a phone interview with HR recruiter to confirm answers to questions, and ask a bit more about interests, experience. Approximately 15 minutes long. Told my notes would be passed on to the team in the office who would decide whether or not to further interview me (coding interview online, then coding interview in the office). E-mailed back within 5 days to say I had been rejected.
