It was one of the best experiences I've had interviewing for a software company.

The whole process, including the initial screens, travel arrangements, and interviews at the office, was handled perfectly by one of Spotify's recruiters in Stockholm. I always felt welcomed.

I had an initial non-technical phone call to see if the role was a good match for me and the company. This was followed by one online interview with two data engineers at Spotify Stockholm.

After that, I was taken to their Stockholm offices where I completed:

• Three technical interviews (programming, systems design, and a case interview)
• One cultural interview
• A friendly lunch with some of their engineers

Overall, it was a pretty good experience.

I ended up declining their offer because I realized the position was not a good fit for me at the time. However, I will certainly consider applying again in the future for a different position if my current situation changes.

Write code that counts lines in a file under different constraints, such as memory, disk space, and whether the data is in or out of order.

Listen to a real-life issue that Spotify had in the past and guide the interviewers through the process of how you would try to identify and fix the issue.

Write code to test some other code, and explain why you are writing those tests, including which corner cases exist.
