I was contacted by a recruiter through LinkedIn while finishing my studies.

The first part involved understanding my interests, personality, and my reasons for joining Spotify. After this phase, I had another Skype interview with one of the team leads in the Data Infrastructure team to see which area I felt more attracted to.

Once decided, another phase was scheduled by the recruiter with an engineer. This involved solving a variety of technical questions, which covered mostly basic CS, Linux, distributed systems, and network concepts.

Later on, after a couple of weeks, I was notified that although the test was fine, they decided to continue with other candidates.
