In late 2019, I went through a three-step interview process. I was rejected after the final step in Stockholm.

First step: An HR interview (remote) was a quick chat to assess role fit.

The second step was a coding assessment (remote) on Scala, involving a few data engineering tasks that weren't particularly complex.

The last step, an all-day on-site interview, expanded into four one-hour assessments:

1. Case study: Discuss an actual disruption the company experienced and identify the underlying issue.
2. System design: Design a system to support a dashboard showing metrics about played songs with a few filters, from client to server.
3. Whiteboard coding interview: Implement a queue. Discuss distributed map-reduce, how to handle sorting.
4. Behavioral assessment: An interview with psychologists to understand me as a human being in a workplace, I suppose.
