Meta Software Developer Internship interview questions

I got this interview opportunity after I attended the college affair. The requiter was really nice and willing to answer any question I asked. The whole processing was: 1. did not ask any question about my CV 2. test my coding technique directly I solved the problem but the time complexity was too high

Contacted after a career fair--passed an on-campus in-person interview, then had one final stage. On-campus consisted of two coding questions in about 45 minutes. Final was a 45-minute video interview. My recruiter took over 3 weeks to get back with my decision.
