Design

Hello everyone. I am a beginner with system design but need to prep so I am trying to start a 30 day challenge. I am going to try and stay consistent, but even if I miss a day here and there, the end goal is just to practice and get ready for interviewing. Feel free to join along. Note: Reddit only allows 15 minutes for the interview so I had to upload it in parts. I did end up not passing this one, but I am ready for tomorrow.
