Meta Intern - Software Engineer interview questions

Two phone interviews. Was contacted by recruter.

I had two technical interviews, both on the phone since I live in Europe and all of Facebook's development is done in the U.S. They talk to you on the phone while asking questions, then you code in an online text editor of which they can see the results live as well. They're very reasonable during these interviews: when you didn't quite get a question, they'll happily explain it better, if your answer is good but not quite there, they'll point you in the direction they want to hear more details about, and so on.
