I applied online.

I made it to the second interview and was rejected, but they actually gave feedback in the rejection email, so respect to Spotify for that.

The first interview just asked for your work experience background, why you are leaving your job, and why you want to join Spotify.

The second interview was talking about a recent work or personal project, any changes you would do differently, and how you handle scale. Then there were domain questions about the role, which for a web engineer was an HTML question, CSS questions, and a JavaScript question about setTimeout where they showed you code and you described the order of execution. Finally, there was a coding question. It was an easy to medium sliding window LeetCode question.
