Amazon System Design Interview: Music Streaming Service

The interviewer opens

Hi, and thanks for joining. Welcome to your interview for the software engineer role at Amazon. We'll design a system together, and you can sketch on the whiteboard on the right of your screen as you talk. If you need to step out or take a break, the Pause button at the top right will pause the interview.

The problem is a music streaming service, and it's up in the Problem tab now. Please read through it, and ask me anything you'd like clarified before you start drawing.

The problem

Design a music streaming service where millions of listeners can search a large catalog of songs, artists and albums, build playlists, save liked songs to a library, and start playing any track almost instantly.

Must do

• Search songs, artists and albums by name
• Create, edit and delete playlists of tracks
• Like songs and view a personal library of liked songs
• Play any track, starting almost immediately, with seeking within a track

Must hold

• Playback must start almost instantly, even with millions listening at once
• The service should basically never be down, especially playback
