Meta Software Engineer interview questions

1. I was contacted by a Facebook recruiter on LinkedIn. 2. She arranged a coding phone screen. It was about an hour long, and assessed programming & algorithmic problem solving skills. 3. After I passed the phone screen, I was invited to an onsite interview, which was about 6 hours long. Each session lasted about 45 minutes. Five sessions involved programming questions on dynamic programming, data structures, system design, algorithmic complexity. One session was almost purely behavioral, even though I was applying for a software engineering position.
