Meta Software Engineer - Internship interview questions

I had four technical questions in two session. The first session was a little challenging for me while the second session was faily good. I got an emial for next step after 48 hours.

2 Coding interviews. Each was 1 hours long. The interviews gave a brief intro, 45mins for the interview and the remaining time for questions and conversation. There was no behavioral questions the discussion at the end was mainly for my own benefit where the interviewer talked about their experiences
