Meta Software Engineer(Internship) interview questions

Was put in touch with the recruiter through my school. She was slow to respond but always got back to me. My interviewer was based in Europe, and he was interviewing me at 6pm his time. He was inattentive/distracted during my interview and he did not provide any feedback during the interview. The question was a graph question. It wasn't that bad and I finished it relatively quickly and discussed tradeoffs/runtimes/how I could make it more efficient. Though, I definitely was a little nervous and not performing at the top of my game. A few weeks went by, and I was notified I had not been selected to move forward in the interview process. The interviewer sucked, but you can't blame anyone but yourself when interviewing for Meta. Prepare enough & you'll get it.
