Meta Software Engineer (internship) interview questions

Referred to an interview opportunity of software engineer internship at Facebook. I answered several questions via email and chose my availability to set up the interview. There was a prep page for you to brush up your knowledge about data structure and algorithms. There's also interview tips for you. The interview process was just coding two questions and asking the interviewer a question at the end.

There were only two coding questions. It was live coding directly at the interview. The first question was about strings and the second one about binary tree. It was not too hard, very doable.
